JavaWeb浏览器传值乱码

Posted 2020-09-02 tjc123

使用tomcat乱码

1.在tomcat的conf/server.xml中的connector，添加URIEncoding=utf-8; 

<Connector port="8081" protocol="HTTP/1.1" connectionTimeout="200000" URIEncoding="UTF-8"/>

2. 在tomcat的bin/catalina.sh中加JAVA_OPTS

JAVA_OPTS="-Xms1024m -Xmm4096m -Dfile.encoding=utf-8"

CATALINA_OPTS="-Dfile.encoding=utf-8"

3.添加 encoding filter,使得encoding filter就在servlet下面；中间不能有其他filter.

<servlet>

<servlet-name>springmvc</servlet-name>

<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>

</servlet>

<servlet-mapping>

<servlet-name>springmvc</servlet-name>

<url-parttern>*.do</url-parttern>

</servlet-mapping>

<servlet-name>springmvc</servlet-name>

<url-parttern>/web/*</url-parttern>

</servlet-mapping>

<filter>
<filter-name>CharacterEncoding</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>CharacterEncoding</filter-name> 
<url-pattern>/*</url-pattern>
</filter-mapping>
