java中文亂碼的解決方法

方法一：可用于和spring集成的解決中文亂碼問題在web.xml中配置<filter><filter><filter-name>encoding</filter-name><filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class><init-param><param-name>encoding</param-name><param-value>UTF-8</param-value></init-param></filter><filter-mapping><filter-name>encoding</filter-name><url-pattern>/*</url-pattern></filter-mapping>方法二：適用于和struts1集成的，解決中文亂碼問題：用actionServlet解決中文亂碼問題===============================自定義一個Servlet繼承apache的actionServlet在自定義的servlet中的service的方法中添加一段代碼！---例如下面的自定義異常類importorg.apache.struts.action.ActionServlet;importorg.apache.struts.action.ActionServlet;publicclassEncodingActionServletextendsActionServlet{ protectedvoidservice(HttpServletRequestarg0,HttpServletResponsearg1) throwsServletException,IOException{ arg0.setCharacterEncoding("UTF-8"); super.service(arg0,arg1); }}并在web.xml中從新注冊actionServlet<servlet><servlet><servlet-name>action</servlet-name><servlet-class>com.aptech.jb.web.action.EncodingActionServlet</servlet-class><init-param><param-name>config</param-name><param-value>/WEB-INF/struts-config.xml</param-value></init-param><init-param><param-name>debug</param-name><param-value>3</param-value></init-param><init-param><param-name>detail</param-name><param-value>3</param-value></init-param><load-on-startup>0</load-on-startup></servlet><servlet-mapping><servlet-name>action</servlet-name><url-pattern>*.do</url-pattern></servlet-mapping>用EncodingActionServlet替換了apache的actionServlet中心控制器因為自定義的servlet繼承于actionServlet所以他可以替代actionServlet方法三：適用于所有程序用filterpackagepackageorg.lyj.fiter;importjava.io.IOException;importjavax.servlet.Filter;importjavax.servlet.FilterChain;importjavax.servlet.FilterConfig;importjavax.servlet.ServletException;importjavax.servlet.ServletRequest;importjavax.servlet.ServletResponse;publicclassMyFilterimplementsFilter{ publicvoiddestroy(){ } publicvoiddoFilter(ServletRequestarg0,ServletResponsearg1, FilterChainarg2)throwsIOException,ServletException{ arg0.setCharacterEncoding("utf-8"); arg1.setCharacterEncoding("utf-8"); arg2.doFilter(arg0,arg1); } publicvoidinit(FilterConfigarg0)throwsServletException{ //TODOAuto-generatedmethodstub }}Web.xml<filter><filter-name>encoding</filter-name><filter-class>org.lyj.fiter.MyFilter</filter-class>
