1 不停机通过接口切换数据源

@GetMapping("/updateDruidProperty")
@Anonymous
    public AjaxResult updateProperty(){
    
    
        DruidDataSource dataSource = SpringUtils.getBean("masterDataSource");
        try {
    
    
            Properties properties = new Properties();
            // 这里是测试写法，具体的value可以通过请求参数传递过来
            // 例如 http://localhost:8080/test?druid.url="...."&&druid.username="...."&&druid.password="...."
            properties.setProperty("druid.url","jdbc:mysql://127.0.0.1:3306/test?useUnicode=true&characterEncoding=utf8&zeroDateTimeBehavior=convertToNull&useSSL=true&serverTimezone=GMT%2B8");
            properties.setProperty("druid.username","root");
            properties.setProperty("druid.password","root");
            dataSource.restart(properties);
        } catch (SQLException throwables) {
    
    
            throwables.printStackTrace();
        }
        return AjaxResult.success();
    }

2 随便写个接口测试

@GetMapping("/insertUser")
    @Anonymous
    public AjaxResult insertUser(){
    
    
        SysUser user = new SysUser();
        user.setUserName("胡云峰");
        user.setNickName("logicfeng");
        userService.insertUser(user);
        String password = configurableEnvironment.getProperty("spring.datasource.druid.master.password");
        return AjaxResult.success(password);
    }

3 使用apifox测试

3.1 切换数据源前新增数据

• 发起请求
  
• 测试结果
  

3.2 切换数据源

• 发起请求
  

3.3 测试新的数据源新增用户

• 发起请求
  
• 测试结果
