### 解決亂碼1
在@RequestMapping設置編碼

@RequestMapping(value = "/j1",produces = "application/json;charset=utf-8")

解決

### 更好的亂碼解決方式：
我們可以在springmvc的配置文件上添加一段消息StringHttpMessageConverter轉換配置！

<mvc:annotation-driven>
   <mvc:message-converters register-defaults="true">
       <bean class="org.springframework.http.converter.StringHttpMessageConverter">
           <constructor-arg value="UTF-8"/>
       </bean>
       <bean class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">
           <property name="objectMapper">
               <bean class="org.springframework.http.converter.json.Jackson2ObjectMapperFactoryBean">
                   <property name="failOnEmptyBeans" value="false"/>
               </bean>
           </property>
       </bean>
   </mvc:message-converters>
</mvc:annotation-driven>

#### 成功
