首先Java 8的日期类型LocalDate,LocalDateTime,LocalTime在Mybatis中并没有映射关系，为此mybatis推出了一个补丁。

<dependency>
   <groupId>org.mybatis</groupId>
   <artifactId>mybatis-typehandlers-jsr310</artifactId>
   <version>1.0.1</version>
</dependency>

在Controller的方法参数里，如果使用了

@RequestParam("date") LocalDate date

当我们传递参数时，会被当成字符串，抛出异常。需要添加一个Controller增强器

@ControllerAdvice
public class GlobalJava8DateHandler {

    @InitBinder
    protected void initBinder(WebDataBinder binder) {
        binder.registerCustomEditor(Date.class,new PropertyEditorSupport() {
            @Override
            public void setAsText(String text) throws IllegalArgumentException {
                setValue(DateUtils.parse(text,DateUtils.pattern4));
            }
        });
        binder.registerCustomEditor(LocalDate.class, new PropertyEditorSupport() {
            @Override
            public void setAsText(String text) throws IllegalArgumentException {
                setValue(LocalDate.parse(text, DateTimeFormatter.ofPattern("yyyy-MM-dd")));
            }
        });
        binder.registerCustomEditor(LocalDateTime.class, new PropertyEditorSupport() {
            @Override
            public void setAsText(String text) throws IllegalArgumentException {
                setValue(LocalDateTime.parse(text, DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss")));
            }
        });
        binder.registerCustomEditor(LocalTime.class, new PropertyEditorSupport() {
            @Override
            public void setAsText(String text) throws IllegalArgumentException {
                setValue(LocalTime.parse(text, DateTimeFormatter.ofPattern("HH:mm:ss")));
            }
        });
    }
}

@InitBinder，用于request中自定义参数解析方式进行注册，从而达到自定义指定格式参数的目的。
