用MySQL客户端，新建测试数据库
客户端：MySQL Workbench
根pom添加依赖
org.springframework.boot
spring-boot-starter-jdbc
mysql
mysql-connector-java
runtime
package com.example.demo.controller;
import org.springframework.beans.factory.annotation.Autowired;import org.springframework.jdbc.core.JdbcTemplate;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import java.util.List;
@RestController
public class HelloWorldController {
@Autowired
JdbcTemplate jdbcTemplate;
@RequestMapping("/hello")
public String index() {
return "Hello World";
}
@RequestMapping("/setMySQLKey")
public String setMySQLKey(String val) {
String sql = "INSERT INTO test_table(name) VALUES(?)";
jdbcTemplate.update(sql, new Object[]{val});
return "true";
}
@RequestMapping("/getMySQLKey")
public List getMySQLKey() {
String sql = "SELECT name FROM test_table";
List nameList = jdbcTemplate.queryForList(sql, String.class);
return nameList;
}
}
application.properties添加配置
数据库设置
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
spring.datasource.url=jdbc:mysql://xx.xx.xxx.xx:3306/test_db?serverTimezone=UTC&useUnicode=true&characterEncoding=utf8
spring.datasource.username=root
spring.datasource.password=xxxxxx
添加数据：http://localhost:8080/setMySQLKey?val=%E5%BC%A0%E4%B8%89
查询数据：http://localhost:8080/getMySQLKey
