springboot 整合druid，使用postgresql

1.首先引入相關依賴

<dependency>
    <groupId>com.alibaba</groupId>
    <artifactId>druid-spring-boot-starter</artifactId>
    <version>1.1.10</version>
</dependency>
<dependency>
    <groupId>org.postgresql</groupId>
    <artifactId>postgresql</artifactId>
    <scope>runtime</scope>
</dependency>
<dependency>
   <groupId>org.springframework.boot</groupId>
   <artifactId>spring-boot-starter-jdbc</artifactId>
</dependency>

2.配置yml

spring:
  datasource:
    druid:
      driver-class-name: org.postgresql.Driver
      url: jdbc:postgresql://ip:port/**?&ssl=false
      username: postgres
      password: 123456
      initial-size: 1
      max-active: 128
      min-idle: 96
      filter:
        stat:
          log-slow-sql: true
          db-type: postgresql
          enabled: true
3.配置類

@Slf4j
@Configuration
public class DruidConfig {
    @ConfigurationProperties(prefix = "spring.datasource.druid")
    @Bean(destroyMethod = "close", initMethod = "init") //第一次使用，頁面會出現(*) property for user to setup，是因為項目中沒有請求過數據庫，請求一次就不需要括號中的東西了
    public DruidDataSource druid() {
        DruidDataSource druidDataSource = new DruidDataSource();
        return druidDataSource;
    }
    /**
        * 配置druid管理頁面的訪問控制
        * 訪問網址: http://127.0.0.1:7070/druid
        * @return
    */
    @Bean
    public ServletRegistrationBean<Servlet> druidServlet() {
        log.info("init Druid Servlet Configuration");
        ServletRegistrationBean<Servlet> servletRegistrationBean = new ServletRegistrationBean<>();
        servletRegistrationBean.setServlet(new StatViewServlet());  //配置一個攔截器
        servletRegistrationBean.addUrlMappings("/druid/*");    //指定攔截器只攔截druid管理頁面的請求
        HashMap<String, String> initParam = new HashMap<String,String>();
        initParam.put("loginUsername", "admin");    //登錄druid管理頁面的用戶名
        initParam.put("loginPassword", "admin");    //登錄druid管理頁面的密碼
        initParam.put("resetEnable", "true");       //是否允許重置druid的統計信息
        initParam.put("allow", "");         //ip白名單，如果沒有設置或為空，則表示允許所有訪問
        servletRegistrationBean.setInitParameters(initParam);
        return servletRegistrationBean;
    }
    @Bean
    public FilterRegistrationBean<WebStatFilter> filterRegistrationBean() {
        FilterRegistrationBean<WebStatFilter> filterRegistrationBean = new FilterRegistrationBean<WebStatFilter>();
        filterRegistrationBean.setFilter(new WebStatFilter());
        filterRegistrationBean.addUrlPatterns("/*");
        filterRegistrationBean.addInitParameter("exclusions", "*.js,*.gif,*.jpg,*.png,*.css,*.ico,/druid/*");
        return filterRegistrationBean;
     }
