4、App.java文件内容如下:
package org.example;
import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
@MapperScan(basePackages = {"org.example.mapper"})
public class App {
public static void main(String[] args) {
SpringApplication.run(App.class,args);
}
}
5、连接配置
package org.example.util;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.stereotype.Component;
@Component
@ConfigurationProperties(prefix = "spring.datasource.click")
public class ConnectionParamConfig {
private String driverClassName ;
private String url ;
private Integer initialSize ;
private Integer maxActive ;
private Integer minIdle ;
private Integer maxWait ;
private String username;
private String password;
public String getDriverClassName() {
return driverClassName;
}
public void setDriverClassName(String driverClassName) {
this.driverClassName = driverClassName;
}
public String getUrl() {
return url;
}
public void setUrl(String url) {
this.url = url;
}
public Integer getInitialSize() {
return initialSize;
}
public void setInitialSize(Integer initialSize) {
this.initialSize = initialSize;
}
public Integer getMaxActive() {
return maxActive;
}
public void setMaxActive(Integer maxActive) {
this.maxActive = maxActive;
}
public Integer getMinIdle() {
return minIdle;
}
public void setMinIdle(Integer minIdle) {
this.minIdle = minIdle;
}
public Integer getMaxWait() {
return maxWait;
}
public void setMaxWait(Integer maxWait) {
this.maxWait = maxWait;
}
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
}
package org.example.util;
import javax.annotation.Resource;
import com.alibaba.druid.pool.DruidDataSource;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import javax.sql.DataSource;
@Configuration
public class DruidConfig {
@Resource
private ConnectionParamConfig jdbcParamConfig;
/**
* 重写 DataSource
* @return
*/
@Bean
public DataSource dataSource() {
DruidDataSource datasource = new DruidDataSource();
datasource.setUrl(jdbcParamConfig.getUrl());
datasource.setDriverClassName(jdbcParamConfig.getDriverClassName());
datasource.setInitialSize(jdbcParamConfig.getInitialSize());
datasource.setMinIdle(jdbcParamConfig.getMinIdle());
datasource.setMaxActive(jdbcParamConfig.getMaxActive());
datasource.setMaxWait(jdbcParamConfig.getMaxWait());
datasource.setUsername(jdbcParamConfig.getUsername());
datasource.setPassword(jdbcParamConfig.getPassword());
return datasource;
}
}
6、service代码如下:
package org.example.service;
import org.example.entity.UserInfo;
import org.example.mapper.UserInfoMapper;
import org.springframework.stereotype.Service;
import javax.annotation.Resource;
import java.util.List;
@Service
public class UserInfoService {
@Resource
private UserInfoMapper userInfoMapper ;
public void saveData(UserInfo userInfo) {
userInfoMapper.saveData(userInfo);
}
public UserInfo selectById(Integer id) {
return userInfoMapper.selectById(id);
}
public List<UserInfo> selectList() {
return userInfoMapper.selectList();
}
}
7、mapper代码如下:
package org.example.mapper;
import org.apache.ibatis.annotations.Mapper;
import org.apache.ibatis.annotations.Param;
import org.example.entity.UserInfo;
import java.util.List;
@Mapper
public interface UserInfoMapper {
void saveData (UserInfo userInfo) ;
UserInfo selectById (@Param("id") Integer id) ;
List<UserInfo> selectList () ;
}
8、UserInfo代码如下:
package org.example.entity;
public class UserInfo {
private int id;
private String userName;
private String passWord;
private String phone;
private String createDay;
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getUserName() {
return userName;
}
public void setUserName(String userName) {
this.userName = userName;
}
public String getPassWord() {
return passWord;
}
public void setPassWord(String passWord) {
this.passWord = passWord;
}
public String getPhone() {
return phone;
}
public void setPhone(String phone) {
this.phone = phone;
}
public String getCreateDay() {
return createDay;
}
public void setCreateDay(String createDay) {
this.createDay = createDay;
}
}
9、controller代码如下:
package org.example.controller;
import org.example.entity.UserInfo;
import org.example.service.UserInfoService;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;
import javax.annotation.Resource;
import java.util.List;
@RestController
public class UserInfoController {
@Resource
private UserInfoService userInfoService ;
//localhost:7010/saveData
@GetMapping("/saveData")
public String saveData (){
UserInfo userInfo = new UserInfo() ;
userInfo.setId(4);
userInfo.setUserName("xiaolin");
userInfo.setPassWord("54321");
userInfo.setPhone("18500909876");
userInfo.setCreateDay("2022-02-06");
userInfoService.saveData(userInfo);
return "success";
}
//localhost:7010/getById?id=1
@GetMapping("/getById")
public UserInfo getById (int id) {
return userInfoService.selectById(id) ;
}
@GetMapping("/getList")
public List<UserInfo> getList () {
return userInfoService.selectList() ;
}
}
10、启动APP,验证
10.1、访问http://localhost:7010/getById?id=1
查看数据库的数据
