springboot 配置 servlet filter 2

springboot 配置 servlet filter 2

以配置Druid为例

Servlet

@WebServlet(
        urlPatterns = "/druid/*",
        initParams = {
                @WebInitParam(name = "loginUsername", value = "admin"),// 登录用户名
                @WebInitParam(name = "loginPassword", value = "123456"),// 登录密码
                @WebInitParam(name = "resetEnable", value = "false"),// 禁用HTML页面上“Reset All”功能
                @WebInitParam(name = "deny", value = ""), // ip黑名单（deny优于allow）,多个用,隔开
                @WebInitParam(name = "allow", value = "127.0.0.1")// IP白名单（没有配置或则为空，则允许访问所有）,多个用,隔开
        })
public class DruidStatViewServlet extends StatViewServlet {

}

Filter

@WebFilter(
        filterName = "druidWebStatFilter",
        urlPatterns = {"/*"},
        initParams = {
                @WebInitParam(name = "exclusions", value = "*.js,*.jpg,*.png,*.gif,*.ico,*.css,/druid/*")
        }
)
public class DruidStatFilter extends WebStatFilter {
}

Config

@Configuration
@ServletComponentScan // 用于扫描所有的Servlet、filter、listener
public class DruidConfiguration {
    /**
     * 加载时读取指定的配置信息,前缀为spring.datasource.druid
     * @return
     */
    @Bean
    @ConfigurationProperties(prefix = "spring.datasource")
    public DataSource druidDataSource() {
        return new DruidDataSource();
    }
}
