SpringBoot使用Spring-JDBC，并配置Druid监控记录

            org.springframework.boot
            spring-boot-starter-web
        

        
        
            org.springframework.boot
            spring-boot-starter-jdbc
        
        
        
            mysql
            mysql-connector-java
            8.0.18
        
        
        
            com.alibaba
            druid
            1.1.23
        
        
            org.projectlombok
            lombok
            true
        

spring:
  datasource:
    type: com.alibaba.druid.pool.DruidDataSource
    initialSize: 5
    minIdle: 5
    maxActive: 20
    maxWait: 60000
    timeBetweenEvictionRunsMillis: 60000
    minEvictableIdleTimeMillis: 300000
    validationQuery: SELECt 1 FROM DUAL
    testWhileIdle: true
    testOnBorrow: false
    testOnReturn: false
    poolPreparedStatements: true
    #   配置监控统计拦截的filters
    filters: stat
    maxPoolPreparedStatementPerConnectionSize: 20
    useGlobalDataSourceStat: true
    connectionProperties: druid.stat.mergeSql=true;druid.stat.slowSqlMillis=500
    driver-class-name: com.mysql.cj.jdbc.Driver
    url: jdbc:mysql://localhost:3306/test?serverTimezone=Asia/Shanghai&useUnicode=true&characterEncoding=utf-8&useSSL=false
    username: root
    password: 123456

druid配置

@Configuration
public class DruidConfig {
    
    @Bean
    @ConfigurationProperties(prefix = "spring.datasource")
    public DruidDataSource druid() {
        return new DruidDataSource();
    }

    
    @Bean
    public ServletRegistrationBean statViewServlet() {
        ServletRegistrationBean bean = new ServletRegistrationBean(new StatViewServlet());
        Map initParams = new HashMap<>();
        initParams.put("loginUsername", "admin");
        initParams.put("loginPassword", "123");
        initParams.put("allow","127.0.0.1");
        bean.setInitParameters(initParams);
        bean.setUrlMappings(Arrays.asList("/druid
    @Test
    void contextLoads() throws Exception{
        System.out.println("------------"+dataSource.getClass()+"------------");

        Connection connection = dataSource.getConnection();

        System.out.println("-------------"+connection+"-----------");
        connection.close();
    }

}

使用sql

@Controller
public class controller {

    @Autowired
    JdbcTemplate jdbcTemplate;

    
    @ResponseBody
    @RequestMapping("/list")
    public List> userslist(){
        String sql = "select * from users";
        List> maps = jdbcTemplate.queryForList(sql);
        return maps;
    }

    @ResponseBody
    @GetMapping("/query")
    public Map map() {
        List> list = jdbcTemplate.queryForList("select * FROM user");
        return list.get(0);
    }

}

sql监控
