ssm中springmvc @Responsebody注释内容返回中文乱码

ssm从前端接收数据处理业务逻辑后返回给前端会经过处理器的一个东西，处理器的职责就是处理编码格式等问题，很多时候需要我们在springmvc的配置文件中配置处理器来满足特殊需求

解决乱码：(一定要注意你的spring的版本，版本不一样配置的类和jar就不一样。。。下面是spring3+)  
pom文件中引入以下两个包:

<dependency>
                <groupId>org.codehaus.jackson</groupId>
                <artifactId>jackson-mapper-asl</artifactId>
                <version>1.9.13</version>
            </dependency>
            <dependency>
                <groupId>org.codehaus.jackson</groupId>
                <artifactId>jackson-core-asl</artifactId>
                <version>1.9.13</version>
            </dependency>

springmvc的配置文件中：(注意这段代码的位置，必须要位于mvc:annotation-driven标签之上才会生效)

<bean class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter">
            <property name="messageConverters">
                <list>
                    <bean class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter" />
                    <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>
                </list>
            </property>
        </bean>

spring4+的乱码解决：

引入jar:

<dependency>
                <groupId>com.fasterxml.jackson.core</groupId>
                <artifactId>jackson-databind</artifactId>
                <version>2.7.4</version>
            </dependency>
            <dependency>
                <groupId>com.fasterxml.jackson.core</groupId>
                <artifactId>jackson-core</artifactId>
                <version>2.7.4</version>
            </dependency>
            <dependency>
                <groupId>com.fasterxml.jackson.core</groupId>
                <artifactId>jackson-annotations</artifactId>
                <version>2.7.4</version>
            </dependency>

spring配置文件:

<bean class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter">
            <property name="messageConverters">
                <list>
                    <ref bean="jsonConverter"></ref>
                </list>
            </property>
        </bean>
        <bean id="jsonConverter" class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">
            <property name="supportedMediaTypes">
                <list>
                    <value>application/json;charset=UTF-8</value>
                </list>
            </property>
        </bean>
