1.添加插件的依赖
<dependency>
<groupId>com.github.pageHelper</groupId>
<artifactId>pageHelper</artifactId>
<version>5.0.4</version>
</dependency>
<dependency>
<groupId>com.github.pageHelper</groupId>
<artifactId>pageHelper-spring-boot-autoconfigure</artifactId>
<version>1.2.5</version>
</dependency>
<dependency>
<groupId>com.github.pageHelper</groupId>
<artifactId>pageHelper-spring-boot-starter</artifactId>
<version>1.2.5</version>
</dependency>
2.添加配置文件
pageHelper.helper-dialect=MysqL
pageHelper.params=count=countsql
pageHelper.reasonable=true
pageHelper.support-methods-arguments=true
3.新建测试类测试
@GetMapping("/list")
@ResponseBody
public PageInfo<User>getUserList(){
//分页起始也页数和条数
pageHelper.startPage(0,5);
//调用查询方法,此时的查询方法已经是分页返回的数据
List<User> list=userService.selectAll();
//封装分页参数返回给前台
PageInfo pageInfo = new PageInfo(list);
return pageInfo;
}
如果失效,可以在pom里面添加aop依赖在试
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-aop</artifactId>
</dependency>
