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();}
}
