SSM解决中文乱码

一、tomcat配置

　　配置tomcat时 设置utf-8编码，主要解决地址栏 url 中文乱码

<!-- 配置tomcat -->
            <plugin>
                <groupId>org.apache.tomcat.maven</groupId>
                <artifactId>tomcat7-maven-plugin</artifactId>
                <version>2.2</version>
                <configuration>
                    <uriEncoding>utf-8</uriEncoding>
                    <useBodyEncodingForURI>true</useBodyEncodingForURI>
                </configuration>
            </plugin>

二、web.xml配置

　　主要解决 request response 中文乱码

<!--中文乱码-->
    <filter>
        <filter-name>characterEncodingFilter</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>characterEncodingFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

三、springmvc.xml配置

　　主要解决request response请求前经过springmvc 导致中文乱码

xmlns:mvc="http://www.springframework.org/schema/mvc"


 xsi:schemaLocation="http://www.springframework.org/schema/mvc
   http://www.springframework.org/schema/mvc/spring-mvc.xsd”



<!-- springmvc @responseBoyd乱码及返回自定义对象 -->
    <mvc:annotation-driven>
        <mvc:message-converters register-defaults="true">
            <bean class="org.springframework.http.converter.StringHttpMessageConverter">
                <property name="supportedMediaTypes">
                    <list>
                        <value>text/plain;charset=UTF-8</value>
                        <value>text/html;charset=UTF-8</value>
                    </list>
                </property>
            </bean>
            
            <bean class="com.alibaba.fastjson.support.spring.FastJsonHttpMessageConverter">
                <property name="supportedMediaTypes">
                    <list>
                        <value>text/html;charset=UTF-8</value>

                </property>
                <property name="features">
                    <array>
                        <!-- 下面配置，默认是false -->
                        <value>WriteMapNullValue</value>
                        <value>WriteNullNumberAsZero</value>
                        <value>WriteNullListAsEmpty</value>
                        <value>WriteNullStringAsEmpty</value>
                        <value>WriteNullBooleanAsFalse</value>
                        <value>WriteDateUseDateFormat</value>
                    </array>
                </property>
            </bean>
        </mvc:message-converters>
    </mvc:annotation-driven>
