3. The incoming backend needs to be encoded in the Web. Xml format

<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>

4. The return value garbled problem needs to be configured in spring MVC XML

<!--fix JSON @Respone return value garbled problem--
<bean class= "org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping"/>

<bean class= "Org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter" >

<property name= "Messageconverters" >

<list>

<bean class = "Org.springframework.http.converter.StringHttpMessageConverter" >

<constructor-arg>

<bean class= "Org.springframework.beans.factory.config.MethodInvokingFactoryBean" >

<property name= "Targetclass" value= "Java.nio.charset.Charset"/>

<property name= "Targetmethod" value= "forname"/>

<property name= "Arguments" value= "UTF-8"/>

</bean>

</constructor-arg>

</bean>

</list>

</property>

5. Finally, Spring MVC redirect parameter garbled problem

Resolution in the Tomcat directory Conf-->server.xml

Plus uriencoding= "UTF-8" on the line.

<connector connectiontimeout= "20000" port= "Up" protocol= "http/1.1" redirectport= "8443" URIEncoding= "UTF-8"/>
