Java - Spring MVC in garbage problem

By default, SpringMVC not high for Chinese support, it is prone to Chinese garbled.

garbled reasons web applications:
Tomcat default character set ISO-8859-1, belonging to the Western European character set does not support Chinese.

The core idea is to solve the garbage to convert ISO-8859-1 to UTF-8.

The Controller requests and responses need to set UTF-8 character set, perfect to solve the garbage problem.

Get garbled request: In the Tomcat server.xml configuration file to increase URLEncoding property.
Post request distortion: CharacterEncodingFilter arranged in web.xml.
Garbled response Response: Configuration message StringHttpMessageConverter converter.

(1) request to resolve get garbled

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

In Tomcat 8.0 or later default is to use UTF-8, so 8.0 or later may not need to configure.

 

(2) post request distortion solution

Add filters in web.xml

<filter>
    <filter-name>characterFilter</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>
</filter>
<filter-mapping>
    <filter-name>characterFilter </ filter-name > 
    <-! intercepts all the URL of -> 
    < url-pattern > / * </ url-pattern > 
</ filter-Mapping >

 

(3) to solve the Chinese garbled response

In applicationContext.xml file, add a converter.

<mvc:annotation-driven conversion-service="conversionService">
    <mvc:message-converters>
        <!--StringHttpMessageConverter对响应中的文本消息进行转换-->
        <bean class="org.springframework.http.converter.StringHttpMessageConverter">
            <property name="supportedMediaTypes">
                <list>
                    <value>test/html;charset=utf-8</value>
                </list>
            </property>
        </bean>
    </mvc:message-converters>
</mvc:annotation-driven>
