jboss7 页面请求参数过多导致报错的的解决方法

今天使用jboss在页面提交一个保存数据的请求，报错了，错误信息如下：

14:36:35,702 ERROR [org.apache.catalina.core.ContainerBase.[jboss.web].[default-host].[/PolicyManager].[dispatcherServlet]] (http--0.0.0.0-8080-1) Servlet.service() for servlet dispatcherServlet threw exception: java.lang.IllegalStateException: More than the maximum number of request parameters (GET plus POST) for a single request ([512]) were detected. Any parameters beyond this limit have been ignored. To change this limit, set the maxParameterCount attribute on the Connector.at org.apache.tomcat.util.http.Parameters.addParameter(Parameters.java:199) [jbossweb-7.0.13.Final.jar:]at org.apache.tomcat.util.http.Parameters.processParameters(Parameters.java:383) [jbossweb-7.0.13.Final.jar:]at org.apache.tomcat.util.http.Parameters.processParameters(Parameters.java:229) [jbossweb-7.0.13.Final.jar:]at org.apache.catalina.connector.Request.parseParameters(Request.java:2874) [jbossweb-7.0.13.Final.jar:]at org.apache.catalina.connector.Request.getParameter(Request.java:1291) [jbossweb-7.0.13.Final.jar:]at org.apache.catalina.connector.RequestFacade.getParameter(RequestFacade.java:363) [jbossweb-7.0.13.Final.jar:]at org.springframework.web.servlet.i18n.LocaleChangeInterceptor.preHandle(LocaleChangeInterceptor.java:67) [spring-webmvc-4.1.6.RELEASE.jar:4.1.6.RELEASE]at org.springframework.web.servlet.HandlerExecutionChain.applyPreHandle(HandlerExecutionChain.java:134) [spring-webmvc-4.1.6.RELEASE.jar:4.1.6.RELEASE]at org.springframework.web.servlet.DispatcherServlet.doDispatch(DispatcherServlet.java:954) [spring-webmvc-4.1.6.RELEASE.jar:4.1.6.RELEASE]at org.springframework.web.servlet.DispatcherServlet.doService(DispatcherServlet.java:893) [spring-webmvc-4.1.6.RELEASE.jar:4.1.6.RELEASE]at org.springframework.web.servlet.FrameworkServlet.processRequest(FrameworkServlet.java:966) [spring-webmvc-4.1.6.RELEASE.jar:4.1.6.RELEASE]at org.springframework.web.servlet.FrameworkServlet.doPost(FrameworkServlet.java:868) [spring-webmvc-4.1.6.RELEASE.jar:4.1.6.RELEASE]at javax.servlet.http.HttpServlet.service(HttpServlet.java:754) [jboss-servlet-api_3.0_spec-1.0.0.Final.jar:1.0.0.Final]at org.springframework.web.servlet.FrameworkServlet.service(FrameworkServlet.java:842) [spring-webmvc-4.1.6.RELEASE.jar:4.1.6.RELEASE]at javax.servlet.http.HttpServlet.service(HttpServlet.java:847) [jboss-servlet-api_3.0_spec-1.0.0.Final.jar:1.0.0.Final]at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:329) [jbossweb-7.0.13.Final.jar:]at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:248) [jbossweb-7.0.13.Final.jar:]at org.springframework.web.filter.CharacterEncodingFilter.doFilterInternal(CharacterEncodingFilter.java:85) [spring-web-4.1.6.RELEASE.jar:4.1.6.RELEASE]at org.springframework.web.filter.OncePerRequestFilter.doFilter(OncePerRequestFilter.java:107) [spring-web-4.1.6.RELEASE.jar:4.1.6.RELEASE]at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:280) [jbossweb-7.0.13.Final.jar:]at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:248) [jbossweb-7.0.13.Final.jar:]at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:275) [jbossweb-7.0.13.Final.jar:]at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:161) [jbossweb-7.0.13.Final.jar:]at org.jboss.as.web.security.SecurityContextAssociationValve.invoke(SecurityContextAssociationValve.java:153) [jboss-as-web-7.1.1.Final.jar:7.1.1.Final]at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:155) [jbossweb-7.0.13.Final.jar:]at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:102) [jbossweb-7.0.13.Final.jar:]at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:109) [jbossweb-7.0.13.Final.jar:]at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:368) [jbossweb-7.0.13.Final.jar:]at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:877) [jbossweb-7.0.13.Final.jar:]at org.apache.coyote.http11.Http11Protocol$Http11ConnectionHandler.process(Http11Protocol.java:671) [jbossweb-7.0.13.Final.jar:]at org.apache.tomcat.util.net.JIoEndpoint$Worker.run(JIoEndpoint.java:930) [jbossweb-7.0.13.Final.jar:]at java.lang.Thread.run(Thread.java:745) [rt.jar:1.7.0_67]

错误的意思就是请求参数超过了最大请求参数数量，需要修改maxParameterCount配置。上网找了一下，原来只需要在jboss的standalone.xml文件中增加一个配置即可

 <system-properties>        <property name="org.apache.catalina.connector.URI_ENCODING" value="UTF-8"/>        <property name="org.apache.catalina.connector.USE_BODY_ENCODING_FOR_QUERY_STRING" value="true"/><!-- 最大请求参数数量配置-->        <property name="org.apache.tomcat.util.http.Parameters.MAX_COUNT" value="5000"/>    </system-properties>

即增加：

<property name="org.apache.tomcat.util.http.Parameters.MAX_COUNT" value="5000"/>
