【Java闭关修炼】SpringBoot-SpringBoot整合其他框架

SpringBoot整合Junit

实现步骤

用于单元测试

• 首先编写一个业务类 UserService

package com.itheima.service;


import org.springframework.stereotype.Service;

@Service
public class UserService {

    public void add(){
        System.out.println("add...");
    }

}

• 编写测试类

package com.itheima.test;


// userService的测试类
import com.itheima.DemoSpring1Application;
import com.itheima.service.UserService;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;


// 注解 需要 添加springboot 引导类

@RunWith(SpringRunner.class)
@SpringBootTest(classes = DemoSpring1Application.class)
public class UserServiceTest {


//     注入userService  调用add方法
    @Autowired
    private UserService userService;

    @Test
    public void testAdd(){
        userService.add();// 测试add
    }

}

Springboot整合redis

创建新的工程 勾选redis

查看依赖redis

package com.itheima.springredis;

import org.junit.jupiter.api.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.data.redis.core.BoundValueOperations;
import org.springframework.data.redis.core.RedisTemplate;

@SpringBootTest
class SpringRedisApplicationTests {

//     注入redisTemplate
    @Autowired
    private RedisTemplate redisTemplate;

    @Test
    void testSet() {
        // 存入数据
        redisTemplate.boundValueOps("name").set("zhangsan");
    }

    @Test
    void testGet() {
        // 获取数据
        Object name = redisTemplate.boundValueOps("name").get();// 通过key获取数据
    }

}

Springboot整合mybatis

勾选依赖

MySQL Driver MyBatis FrameWork

配置datasource数据源信息

创建application.yml文件 填写配置信息

spring:
  datasource:
    url: jdbc:mysql:///db111
    username: root
    password: 123456
    driver-class-name: com.mysql.jdbc.Driver

定义Mapper接口

使用Mapper接口操作数据库

package com.itheima.springbootmybatis.mapper;
import com.itheima.springbootmybatis.domain.User;
import org.apache.ibatis.annotations.Mapper;
import org.apache.ibatis.annotations.Select;
import org.springframework.boot.autoconfigure.security.SecurityProperties;

import java.util.List;

@Mapper
public interface UserMapper {

//     查询所有用户
    @Select("select * from user")
    public List<User> findAll();

}

测试

在引导类注入Mapper接口 进行测试

package com.itheima.springbootmybatis;

import com.itheima.springbootmybatis.domain.User;
import com.itheima.springbootmybatis.mapper.UserMapper;
import org.apache.ibatis.annotations.Mapper;
import org.junit.jupiter.api.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;

import java.util.List;

@SpringBootTest
class SpringbootMybatisApplicationTests {
    @Autowired
    private UserMapper userMapper;// 注入Mapper接口资源

    @Test
    public void testFindAll(){
        // 调用接口方法
        List<User> all = userMapper.findAll();
        System.out.println(all);
    }

    @Test
    void contextLoads() {
    }

}

UserXmlMapper配置

• UserXmlMapper

package com.itheima.springbootmybatis.mapper;


import com.itheima.springbootmybatis.domain.User;
import org.apache.ibatis.annotations.Mapper;
import org.springframework.stereotype.Repository;

import java.util.List;

@Mapper
@Repository
public interface UserXmlMapper {
    public List<User> findAll();
}

映射配置文件

# datasource配置
spring:
  datasource:
    url: jdbc:mysql:///db11?serverTimezone=UTC
    username: root
    password: 123456
    driver-class-name: com.mysql.cj.jdbc.Driver


# 指定mybatis的核心配置文件
mybatis:
  mapper-locations: classpath:mapper/*Mapper.xml  # mapper映射文件路径
  type-aliases-package: com.itheima.springbootmybatis.domain
#  config-location:

利用springboot整合Mybatis测试

package com.itheima.springbootmybatis;

import com.itheima.springbootmybatis.domain.User;
import com.itheima.springbootmybatis.mapper.UserMapper;
import com.itheima.springbootmybatis.mapper.UserXmlMapper;
import org.apache.ibatis.annotations.Mapper;
import org.junit.jupiter.api.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;

import java.util.List;

@SpringBootTest
class SpringbootMybatisApplicationTests {
    @Autowired
    private UserMapper userMapper;// 注入Mapper接口资源

    @Autowired
    private UserXmlMapper userXmlMapper;

    @Test
    public void testFindAll(){
        // 调用接口方法
        List<User> all = userMapper.findAll();
        System.out.println(all);
    }

    @Test
    public void testFindAll1(){
        // 调用接口方法
        List<User> all = userXmlMapper.findAll();
        System.out.println(all);
    }

    @Test
    void contextLoads() {
    }

}
