how to solve url request encoding problems

We may have trouble with the code, and we can try to solve the problem by using the following method.

解决乱码问题

比如我们请求夏目按的接口，但是传递的参数有中文可能导致写入数据库乱码，这样应该怎么解决呢？

    http://localhost:8080/manage/category/add_category.do?parentId=0&categoryName=家庭用品

请求上面一的url时候，写入数据库时乱码的，数据库编码设置成utf-8,打开my.ini 方法：

 [client]

 default_character_set = utf8

 [mysqld]

 port= 3306

 character-set-server = utf8

 collation-server = utf8_general_ci

 [mysql]

 default_character_set = utf8

配置过滤器

<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>

修改tomcat的编码！！

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