idea使用maven从0整合ssm+shiro

1. 搭建环境

idea2017

maven3

jdk1.8

2. 整合ssm

  1. 首先新建一个maven工程,空的也无所谓,构建目录结构,如图1.

    这里写图片描述

    构建maven工程的类型,可以在project structure里面看到,如图2所示

    目录搭建好了,可以开始整合ssm了。

    首先把jar给导入,maven就是帮我们干这个事情的。除了jar包的依赖管理,还有编译的一些配置可以设置。我把我的maven的pom.xml给贴上来吧。如果不知道怎么弄maven,你可以先去看一下idea 配置maven的blog。如果是eclipse的话,请你走吧,我试过帮我同学弄,出现很多问题,比如xsd重复这些,如果你是新手eclipse和idea都不熟悉,你还是下载idea吧。然后边百度边使用idea。

    jar包导进来了。你可能会问这么多jar包啊,我怎么知道。对不起,我也是百度过来的。有些jar包我知道,有些我不知道。抱歉。

    继续。web工程都先看WEB-INF下面的web.xml的配置,无论哪个web工程。

    那么我先把我整理过的web.xml贴上来。

    <?xml version="1.0" encoding="UTF-8"?>
    <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
             xmlns="http://java.sun.com/xml/ns/javaee"

             version="3.0">
      <display-name>ssm</display-name>
      <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:./spring-cfg.xml</param-value>
      </context-param>
    
      <!-- 编码过滤器 -->
      <filter>
        <filter-name>encodingFilter</filter-name>
        <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
        <async-supported>true</async-supported>
        <init-param>
          <param-name>encoding</param-name>
          <param-value>UTF-8</param-value>
        </init-param>
      </filter>
      <filter-mapping>
        <filter-name>encodingFilter</filter-name>
        <url-pattern>/*</url-pattern>
      </filter-mapping>
      <!-- Spring监听器 -->
      <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
      </listener>
      <!-- Spring MVC servlet -->
      <servlet>
        <servlet-name>SpringMVC</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
          <param-name>contextConfigLocation</param-name>
          <param-value>classpath:spring-mvc.xml</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
        <async-supported>true</async-supported>
      </servlet>
      <servlet-mapping>
        <servlet-name>SpringMVC</servlet-name>
        <url-pattern>/</url-pattern>
      </servlet-mapping>
      <!--log4j日誌-->
      <context-param>
        <param-name>log4jConfigLocation</param-name>
        <param-value>classpath:log4j.properties</param-value>
      </context-param>
    </web-app>
    
    

    稍微来说明一下吧。<display-name>ssm</display-name>工程名。

    下面这个,springcontext的配置文件,很重要,一般把这个配置文件独立出去,方便管理,事实上你写到web.xml里面来也是没有什么问题的。但是我没有试过。有兴趣了解一下?然后告诉我?

      <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:./spring-cfg.xml</param-value>
      </context-param>
    

    接下来就是编码过滤器。事实上就是一个filter,因为Tomcat的默认编码不是utf-8

    所以为了保证编码的一致,使用这个编码过滤器,<filter-mapping>代表的过滤器的生效路径。

    <filter>
        <filter-name>encodingFilter</filter-name>
        <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
        <async-supported>true</async-supported>
        <init-param>
          <param-name>encoding</param-name>
          <param-value>UTF-8</param-value>
        </init-param>
      </filter>
      <filter-mapping>
        <filter-name>encodingFilter</filter-name>
        <url-pattern>/*</url-pattern>
      </filter-mapping>
    

    接下来就是spring的监听器了,**ContextLoaderListener的作用就是启动Web容器时,自动装配ApplicationContext.xml的配置信息。**因为它实现了ServletContextListener这个接口,在web.xml配置这个监听器,启动容器时,就会默认执行它实现的方法。

    也就是说,当web容器初始化的时候,spring 的配置文件ApplicationContext.xml也启用了,当然我这里spring的配置文件是spring-cfg.xml。所以监听器决定我们spring是否启动。

    https://www.cnblogs.com/wuchaodzxx/p/6038895.html

    <!-- Spring监听器 -->
      <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    

这里写图片描述

继续下一个,就是servlet的配置了,servlet是web的基础,我们没有用框架的时候,就是在web.xml里面配置servlet-class和servlet-mapping的。那么这里的配置就是吧servlet交给springMVC的dispatcherServlet类。适配路径/* 全部路径。就是说所有的url都会进入到dispatchservlet类里面。但你配置 /su/*的时候,那就只能适配/su/ 后面的路径了

这里就是实现了整合springMVC,而上面就是整合了spring,那么你会问mybatis捏,事实上mybatis是后端和数据交互的中间过程,也是说桥梁。那么我们写业务的时候才需要用到mybatis,所以mybatis是整合到spring里面来,也就是说实在spring-cfg.xml里面配置。

<!-- Spring MVC servlet -->
  <servlet>
    <servlet-name>SpringMVC</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
      <param-name>contextConfigLocation</param-name>
      <param-value>classpath:spring-mvc.xml</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
    <async-supported>true</async-supported>
  </servlet>
  <servlet-mapping>
    <servlet-name>SpringMVC</servlet-name>
    <url-pattern>/</url-pattern>
  </servlet-mapping>

那么接下来就是spring-cfg.xml了,这配置也就是开启aop,扫描注解开启,事务开启。还有整合mybatis,整合就是配置sqlSessionFactory以及扫描mapper。当然你说用xml注入bean也行,我开了注解就注入,然而用xml配置DI我觉得好麻烦,而且又长。打注解比较方便,相比之下。

</beans>

接下来就是spring-mvc.xml。开启注解,开启包扫描注解,包扫描component,主要是扫描controller,处理静态资源,以及配置处理器,这里我用的velocity,以前很多人用jsp。我没有导jstl的jar包,你要你自己找dependency导进来。再自己配置

</beans>

到了这里还没好,扫描的那些mapper文件没有,entity也没有,dao也没有,这些没有还会会报错。继续看下去,你可以用mybatis-generator逆向,不会的自行百度。

我这里简单说一下。

主要是pom.xml的那里吧mybatis-generator导进来。

然后配置xml,再配置maven

配置文件generatorConfig.xml为

<?xml version="1.0" encoding="UTF-8" ?>

        </table>



    </context>
</generatorConfiguration>

这里写图片描述

逆向生成后,自己写一些controller测试吧。到这里已经搭建好了

如果报错,查看报错信息,先翻译找错,不行再百度吧。

3.整合logback+lombok

首先是pom.xml导包,这里只是pom.xml的一部分,这是logback需要的一些包

 <!-- 日志文件管理包 -->
        <!-- log start -->

        <!--logback-->
        <dependency>
            <groupId>org.slf4j</groupId>
            <artifactId>slf4j-api</artifactId>
            <version>${slf4j.version}</version>
        </dependency>
        <dependency>
            <groupId>ch.qos.logback</groupId>
            <artifactId>logback-core</artifactId>
            <version>1.1.6</version>
        </dependency>
        <dependency>
            <groupId>ch.qos.logback</groupId>
            <artifactId>logback-classic</artifactId>
            <version>1.1.6</version>
        </dependency>
        <dependency>
            <groupId>ch.qos.logback</groupId>
            <artifactId>logback-access</artifactId>
            <version>1.1.2</version>
        </dependency>
        <dependency>
            <groupId>commons-logging</groupId>
            <artifactId>commons-logging</artifactId>
            <version>1.2</version>
        </dependency>

        <dependency>
            <groupId>commons-codec</groupId>
            <artifactId>commons-codec</artifactId>
            <version>1.10</version>
        </dependency>

        <dependency>
            <groupId>log4j</groupId>
            <artifactId>log4j</artifactId>
            <version>1.2.17</version>
        </dependency>
        <dependency>

        </dependency>
        <dependency>
            <groupId>org.projectlombok</groupId>
            <artifactId>lombok</artifactId>
            <version>1.16.6</version>
        </dependency>
        <!--end-->

配置logback,新建一个logback.xml,这里面有些地方需要改写自己项目的配置,比如日志存放的文件的位置,默认是Tomcat的启动的那个盘的目录下,我的配置是这样子的。logback的好处,自己去百度吧,这里是采用error级别和info级别的区分,有特定需求自己搞吧。

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
    <property name="LOG_HOME" value="/logs/ssm/" />

    <appender name="Console" class="ch.qos.logback.core.ConsoleAppender">
        <encoder>
            <pattern>%d{H:mm} %-5level [%logger{16}] %msg%n</pattern>
        </encoder>
    </appender>

    <appender name="normalLog"
              class="ch.qos.logback.core.rolling.RollingFileAppender">
        <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
            <FileNamePattern>${LOG_HOME}/web.normal.%d{yyyy-MM-dd}.log
            </FileNamePattern>
            <MaxHistory>30</MaxHistory>
        </rollingPolicy>
        <triggeringPolicy class="ch.qos.logback.core.rolling.SizeBasedTriggeringPolicy">
            <maxFileSize>10MB</maxFileSize>
        </triggeringPolicy>
        <layout class="ch.qos.logback.classic.PatternLayout">
            <pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger{16} - %msg%n
            </pattern>
        </layout>
        <filter class="ch.qos.logback.classic.filter.LevelFilter">
            <level>ERROR</level>
            <onMatch>DENY</onMatch>
            <onMismatch>ACCEPT</onMismatch>
        </filter>
    </appender>
    <appender name="errorLog"
              class="ch.qos.logback.core.rolling.RollingFileAppender">
        <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
            <FileNamePattern>${LOG_HOME}/web.error.%d{yyyy-MM-dd}.log
            </FileNamePattern>
            <MaxHistory>30</MaxHistory>
        </rollingPolicy>
        <triggeringPolicy class="ch.qos.logback.core.rolling.SizeBasedTriggeringPolicy">
            <maxFileSize>10MB</maxFileSize>
        </triggeringPolicy>
        <layout class="ch.qos.logback.classic.PatternLayout">
            <pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger{16} - %msg%n
            </pattern>
        </layout>
        <filter class="ch.qos.logback.classic.filter.LevelFilter">
            <level>ERROR</level>
            <onMatch>ACCEPT</onMatch>
            <onMismatch>DENY</onMismatch>
        </filter>
    </appender>


    <logger name="com.su" level="debug" >
        <appender-ref ref="normalLog" />
        <appender-ref ref="errorLog" />
    </logger>


    <root level="info">
        <appender-ref ref="Console" />
    </root>
</configuration>

然后在web.xml配置logback

  <!--log4j日誌 由于启用了logback日志,此配置废除-->
  <!--<context-param>-->
    <!--<param-name>log4jConfigLocation</param-name>-->
    <!--<param-value>classpath:log4j.properties</param-value>-->
  <!--</context-param>-->


  <!--logback日志-->
  <context-param>
    <param-name>logbackConfigLocation</param-name>
    <param-value>classpath:logback.xml</param-value>
  </context-param>

4. 整合shiro

首先导包。

<!--apache shiro  -->
        <dependency>
            <groupId>org.apache.shiro</groupId>
            <artifactId>shiro-core</artifactId>
            <version>1.2.2</version>
        </dependency>
        <dependency>
            <groupId>org.apache.shiro</groupId>
            <artifactId>shiro-web</artifactId>
            <version>1.2.3</version>
        </dependency>
        <dependency>
            <groupId>org.apache.shiro</groupId>
            <artifactId>shiro-spring</artifactId>
            <version>1.2.3</version>
        </dependency>
        <!--end-->

配置spring-cfg.xml

<!--整合shiro-->
    <!--切面类-->
    <bean class="org.apache.shiro.spring.security.interceptor.AuthorizationAttributeSourceAdvisor"/>

    <!--自定义Realm-->
    <bean id="myRealm" class="com.su.shiro.MyRealm"/>

    <bean id="securityManager" class="org.apache.shiro.web.mgt.DefaultWebSecurityManager">
        <property name="realm" ref="myRealm"/>
    </bean>

创建一个realm,注意这里只是简单创建一个realm,其实可以创建多个realm,这个需要看需求,我把代码贴出来吧,简化过的代码,有需要可以查看别人的博客,来进行完善

package com.su.shiro;



import com.su.user.entity.User;
import com.su.user.service.UserService;
import org.apache.shiro.authc.AuthenticationException;
import org.apache.shiro.authc.AuthenticationInfo;
import org.apache.shiro.authc.AuthenticationToken;
import org.apache.shiro.authc.SimpleAuthenticationInfo;
import org.apache.shiro.authz.AuthorizationInfo;
import org.apache.shiro.authz.SimpleAuthorizationInfo;
import org.apache.shiro.realm.AuthorizingRealm;
import org.apache.shiro.subject.PrincipalCollection;

import javax.annotation.Resource;
import java.util.Set;

/**
 * @author Veng Su 1344114844@qq.com
 * @date 2018/4/12 9:40
 */
public class MyRealm extends AuthorizingRealm {
    @Resource
    private UserService userServiceImpl;

    //为当前登录成功的用户授予权限和角色,已经登录成功了。
    protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principals) {
        String username=(String) principals.getPrimaryPrincipal();
        SimpleAuthorizationInfo authorizationInfo=new SimpleAuthorizationInfo();
        //这里拿到角色名
        Set<String> roles = null;
        roles.add("user");//赋予user角色,其实你可以放到数据库里面,这里简化
        authorizationInfo.setRoles(roles);
        //这里拿到该角色的权限
        //这里拿到角色名
        Set<String> permissions = null;
        permissions.add("select");//赋予user角色权限,其实你可以放到数据库里面,这里简化
        authorizationInfo.setStringPermissions(permissions);
        return authorizationInfo;
    }


    //验证当前登录的用户,获取认证信息。
    protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {
        String username=(String) token.getPrincipal();//获取用户名
        User user=new User();//这里简化,本来从数据库拿的
        //如果查询不出来则返回null,不通过验证,如果查出来,则返回AuthenticationInfo
        if(user!=null){
            AuthenticationInfo authcInfo =new SimpleAuthenticationInfo(user.getUsername(), user.getPassword(),"myRealm");
            return authcInfo;
        }else{
            return null;
        }
    }
}


好了,万事俱备,那么就要在web.xml里面注册这个shiro,shiro是基于filter来搞得,那么就要在web.xml里面注册这个filter

<!--集成shiro-->
    <filter>
        <filter-name>shiroFilter</filter-name>
        <filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
        <init-param>
            <!-- 该值缺省为false,表示声明周期由SpringApplicationContext管理,设置为true表示ServletContainer管理 -->
            <param-name>targetFilterLifecycle</param-name>
            <param-value>true</param-value>
        </init-param>
    </filter>
    <filter-mapping>
        <filter-name>shiroFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

那么到这里,shiro已经集成到spring里面了

接下来就是使用shiro来做登录验证,我去找张流程图

认证过程

这里写图片描述

授权过程

然后,我把构建sercurityManager的环境搭建起来吧,简单点就是用controller调用realm的doGetAuthorizationInfo授权,和doGetAuthenticationInfo验证,这里是我的项目的源码而已,有问题,看着shiro的官方文档来吧

package com.su.shiro;


import com.su.user.service.UserService;
import org.apache.shiro.authc.AuthenticationException;
import org.apache.shiro.authc.AuthenticationInfo;
import org.apache.shiro.authc.AuthenticationToken;
import org.apache.shiro.authz.AuthorizationInfo;
import org.apache.shiro.authz.SimpleAuthorizationInfo;
import org.apache.shiro.realm.AuthorizingRealm;
import org.apache.shiro.subject.PrincipalCollection;

import javax.annotation.Resource;

/**
 * @author Veng Su 1344114844@qq.com
 * @date 2018/4/12 9:40
 */
public class MyRealm extends AuthorizingRealm {
    @Resource
    private UserService userServiceImpl;

    //为当前登录成功的用户授予权限和角色,已经登录成功了。
    protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principals) {
        String username=(String) principals.getPrimaryPrincipal();
        SimpleAuthorizationInfo authorizationInfo=new SimpleAuthorizationInfo();
//        authorizationInfo.setRoles(userServiceImpl.getRoles(username));
//        authorizationInfo.setStringPermissions(userServiceImpl.getPermissions(username));
        return authorizationInfo;
    }


    //验证当前登录的用户,获取认证信息。
    protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {
        String username=(String) token.getPrincipal();//获取用户名
//        User user=userServiceImpl.getByUsername(username);
//        if(user!=null){
//            AuthenticationInfo authcInfo =new SimpleAuthenticationInfo(user.getUsername(), user.getPassword(),"myRealm");
//            return authcInfo;
//        }else{
//            return null;
//        }
        return null;
    }
}
