在application.yml檔案中配置druid的引數是不會生效的

可以自己建立配置類使用@ConfigurationProperties(prefix="spring.datasource")讓其生效

@Configuration
public class DruidConfig {

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

    @Bean
    
 
public ServletRegistrationBean statViewServlet(){
        ServletRegistrationBean registrationBean = new ServletRegistrationBean(new StatViewServlet(),"/druid/*");

        Map<String,String> initParameters = new HashMap<>();
        //設定druid後臺管理名
        initParameters.put("loginUsername","admin");
        
 
//設定druid後臺密碼
        initParameters.put("loginPassword","123");
        //設定白名單
        initParameters.put("allow","");
        //設定給名單，當白名單和黑名單同時存在時，黑名單優先
        initParameters.put("deny","192.168.42.82");
        //將配置引數map載入到InitParameters中
        registrationBean.setInitParameters(initParameters);
        
 
return registrationBean;
    }

    @Bean
    public FilterRegistrationBean s(){
        FilterRegistrationBean registrationBean = new FilterRegistrationBean();
        registrationBean.setFilter(new WebStatFilter());

        Map<String,String> initParameters = new HashMap<>();
        //設定要排除的請求
        initParameters.put("exclusions","*.js,*.css,*.html,/druid/*");

        registrationBean.setInitParameters(initParameters);

        registrationBean.setUrlPatterns(Arrays.asList("/*"));
        return registrationBean;
    }
}

同時在裡面配置了druid後臺管理
