jsp到controller乱码

1：jsp页面的from表单没有写提交方式method="post"

 

2:没有在web.xml在设置编码拦截器（这个拦截器，要放在所有拦截器的最前边）

 

   

 <filter>
    <filter-name>encodingFilter</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>
    <init-param>
      <param-name>forceEncoding</param-name>
      <param-value>true</param-value>
    </init-param>
  </filter>
  <filter-mapping>
   <filter-name>encodingFilter</filter-name>
   <url-pattern>/*</url-pattern>
  </filter-mapping>

　　

 

3：window.localtion.href跳转到controller，参数出错

   1） jsp页面：

  

  window.location.href = "/loan7/casesController/searchForm.do?caseNo="+caseNo+"&productTypeName="+decodeURI(decodeURI(productTypeName));

 

    2）controller层

productTypeName = new String(productTypeName.getBytes("ISO-8859-1"),"UTF-8");

 

4：jsp通过ajax传递中文参数报错

修改tomcat  配置文件conf  下的server.xml
