3. mybatis-plus插件配置核心类
package com.jmh.mp.config;
import com.baomidou.mybatisplus.annotation.DbType;
import com.baomidou.mybatisplus.autoconfigure.ConfigurationCustomizer;
import com.baomidou.mybatisplus.extension.plugins.MybatisPlusInterceptor;
import com.baomidou.mybatisplus.extension.plugins.inner.PaginationInnerInterceptor;
import org.mybatis.spring.annotation.MapperScan;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
@Configuration
public class MybatisPlusConfig {
/**
* 新的分页插件,一缓和二缓遵循mybatis的规则,需要设置 MybatisConfiguration#useDeprecatedExecutor = false 避免缓存出现问题(该属性会在旧插件移除后一同移除)
*/
@Bean
public MybatisPlusInterceptor mybatisPlusInterceptor() {
MybatisPlusInterceptor interceptor = new MybatisPlusInterceptor();
interceptor.addInnerInterceptor(new PaginationInnerInterceptor(DbType.H2));
return interceptor;
}
}4. 启动类配置
package com.jmh.mp;
import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
@MapperScan("com.jmh.mp.mapper")
public class Mp01Application {

- 采用junit测试
package com.jmh.mp;
import com.baomidou.mybatisplus.core.conditions.query.QueryWrapper;
import com.baomidou.mybatisplus.extension.plugins.pagination.Page;
import com.jmh.mp.mapper.UserMapper;
import com.jmh.mp.model.User;
import org.junit.jupiter.api.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
@SpringBootTest
class Mp01ApplicationTests {
@Autowired
private UserMapper userMapper;
@Test
void contextLoads() {
Page<User> userPage = userMapper.selectPage(new Page<User>()
.setCurrent(1)//当前页
.setSize(10)//当前页大小
, new QueryWrapper<User>());
System.out.println("总数据量:" + userPage.getTotal());
System.out.println("当前页码:" + userPage.getCurrent());
System.out.println("当前页大小:" + userPage.getSize());
userPage.getRecords().forEach(System.out::println);
}
}
- 结果
