这篇文章将为大家详细讲解有关Spring Boot对jdbc支持的示例分析,小编觉得挺实用的,因此分享给大家做个参考,希望大家阅读完这篇文章后可以有所收获。
项目结构
pom.xml
pom.xml:
<?xml version="1.0" encoding="UTF-8"?><project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <parent> <artifactId>spring-boot-02</artifactId> <groupId>com.keafmd</groupId> <version>1.0-SNAPSHOT</version> </parent> <modelVersion>4.0.0</modelVersion> <artifactId>spring-boot-08</artifactId> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <!-- 解析jsp类库 --> <dependency> <groupId>org.apache.tomcat.embed</groupId> <artifactId>tomcat-embed-jasper</artifactId> </dependency> <dependency> <groupId>jstl</groupId> <artifactId>jstl</artifactId> <version>1.2</version> </dependency> <!-- JDBC-启动器, 默认的数据源 HikariCP --> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-jdbc</artifactId> </dependency> <!-- JDBC-启动器, 默认的数据源 HikariCP --> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>5.1.46</version> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-devtools</artifactId> </dependency> </dependencies></project>
application.yml
server: port: 80spring: datasource: url: jdbc:mysql://127.0.0.1:3306/ssm-java1?useSSL=false driver-class-name: com.mysql.jdbc.Driver username: root password: 18044229
启动类
package com.keafmd;import org.springframework.boot.SpringApplication;import org.springframework.boot.autoconfigure.SpringBootApplication;@SpringBootApplicationpublic class App08 { public static void main(String[] args) { SpringApplication.run(App08.class, args); }}
Dao层
UserDao:
package com.keafmd;import org.springframework.boot.SpringApplication;import org.springframework.boot.autoconfigure.SpringBootApplication;@SpringBootApplicationpublic class App08 { public static void main(String[] args) { SpringApplication.run(App08.class, args); }}
Service层
IUserService :
package com.keafmd.service;import java.util.List;public interface IUserService { List list();}
UserServiceImpl:
package com.keafmd.service.impl;import com.keafmd.dao.UserDao;import com.keafmd.service.IUserService;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.stereotype.Service;import java.util.List;@Servicepublic class UserServiceImpl implements IUserService { @Autowired UserDao userDao; @Override public List list() { return userDao.userList(); }}
Controller层
UserController:
package com.keafmd.controller;import com.keafmd.service.IUserService;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.RestController;import java.util.List;@RestControllerpublic class UserController { @Autowired IUserService userService; @RequestMapping("userlist") List UserList(){ return userService.list(); }}
测试类测试
UserDaoTest:
package com.keafmd.dao;import com.keafmd.App08;import org.junit.jupiter.api.Test;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.boot.test.context.SpringBootTest;import java.util.List;import static org.junit.jupiter.api.Assertions.*;@SpringBootTest(classes = App08.class)class UserDaoTest { @Autowired UserDao userDao; @Test public void test(){ List userlist = userDao.userList(); for (Object o : userlist) { System.out.println(o); } }}
运行test方法的效果:
运行启动类,测试效果
运行启动类,访问:http://127.0.0.1/userlist
