Jeesite中解决GET请求及POST乱码

我们在使用jeesite进行开发的时候，在CMS中的评论管理中后发现乱码问题，这个乱码是由于GET请求传递中文造成的，我们的解决方案是自定义编码过滤器解决。

相应的代码如下：

package com.thinkgem.jeesite.common.filter;import java.io.IOException;import java.io.UnsupportedEncodingException;import java.util.Map;import javax.servlet.Filter;import javax.servlet.FilterChain;import javax.servlet.FilterConfig;import javax.servlet.ServletException;import javax.servlet.ServletRequest;import javax.servlet.ServletResponse;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletRequestWrapper;public class GetAndPostEncodingFilter implements Filter {@Overridepublic void init(FilterConfig filterConfig) throws ServletException {// TODO Auto-generated method stub}@Overridepublic void doFilter(ServletRequest request, ServletResponse response, FilterChain chain)throws IOException, ServletException {//处理请求乱码HttpServletRequest httpServletRequest = (HttpServletRequest) request;HttpServletRequest myRequest = new MyRequest(httpServletRequest);//处理响应乱码response.setContentType("text/html;charset=utf-8");chain.doFilter(myRequest, response);}@Overridepublic void destroy() {// TODO Auto-generated method stub}}//自定义request对象class MyRequest extends HttpServletRequestWrapper{  private HttpServletRequest request;  private boolean hasEncode;  public MyRequest(HttpServletRequest request) {      super(request);      this.request=request;  }  //对需要增强的方法 进行覆盖  @Override  @SuppressWarnings("unchecked")  public Map<String,String[]> getParameterMap() {      //先获得请求方式      String method = request.getMethod();      if(method.equalsIgnoreCase("post")){   //post方式请求          try {              request.setCharacterEncoding("utf-8");              return request.getParameterMap();          } catch (UnsupportedEncodingException e) {              e.printStackTrace();          }      }else if(method.equalsIgnoreCase("get")){  //get方式请求Map<String,String[]> parameterMap = request.getParameterMap();          if(!hasEncode){              for(String parameterName:parameterMap.keySet()){                  String[] values = parameterMap.get(parameterName);                  if(values!=null){                      for (int i = 0; i < values.length; i++) {                          try {                              values[i] = new String(values[i].getBytes("ISO-8859-1"),"utf-8");                          } catch (UnsupportedEncodingException e) {                              e.printStackTrace();                          }                      }                  }              }              hasEncode =  true;          }          return parameterMap;      }      return super.getParameterMap();  }  @Override  public String getParameter(String name) {      Map<String,String[]> parameterMap = getParameterMap();      String[] values = parameterMap.get(name);      if(values==null){          return null;      }      return values[0];  }  @Override  public String[] getParameterValues(String name) {      Map<String,String[]> parameterMap = getParameterMap();      String[] values=parameterMap.get(name);      return values;  }}

相应的web.xml配置如下：

<!-- 自定义编码过滤器解决POST请求与GET请求乱码问题 --><filter><filter-name>getAndPostEncodingFilter</filter-name><filter-class>com.thinkgem.jeesite.common.filter.GetAndPostEncodingFilter</filter-class></filter><filter-mapping><filter-name>getAndPostEncodingFilter</filter-name><url-pattern>/*</url-pattern></filter-mapping>
