今天写了一个controller

@RequestMapping("/addAUsertype")
	public @ResponseBody Map<String,Object> addAUsertype(@RequestParam String typeId,@RequestParam String typeName,
			@RequestParam Integer maxBorrowNum) 
	{
		Map<String,Object> map = new HashMap<String,Object>();
		Map<String,Object> paramMap = new HashMap<String,Object>();
		try{
			
			paramMap.put("typeId", typeId);
			paramMap.put("typeName", typeName);
			paramMap.put("maxBorrowNum", maxBorrowNum);
			int flag = usertypeservice.addAUsertype(paramMap);
			if(flag == 1)
			{
				map.put(Constants.STATUS, Constants.SUCCESS);
				map.put(Constants.MESSAGE, "添加用户类型成功");	
			}
			else
			{
				map.put(Constants.STATUS, Constants.FAILURE);
				map.put(Constants.MESSAGE, "添加用户类型失败");	
			}
		}
		catch(Exception e)
		{
			e.getStackTrace();
			map.put(Constants.STATUS, Constants.FAILURE);
			map.put(Constants.MESSAGE, "添加用户类型失败");				
		}
		
		return map;
	}

然而在测试的时候http://localhost:8080/pandastore/usertype/addAUsertype.do?typeId=00005&typeName= 教师&maxBorrowNum=100

 接收到的中文参数变为了乱码

解决方法：get方法：在tomcat的server.xml的

<Connector port="8080" protocol="HTTP/1.1"
connectionTimeout="20000"
redirectPort="8443" />

添加URIEncoding="utf-8"
<Connector port="8080" protocol="HTTP/1.1"
connectionTimeout="20000"
redirectPort="8443" URIEncoding="utf-8"/>

post:

web.xml配置一个字符过滤器

    <!-- Spring字符集过滤器 -->
    <filter>
        <filter-name>SpringEncodingFilter</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>SpringEncodingFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>
