使用messageConverters
<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>
在springmvc的配置文件中,将消息转换器的bean放在 <mvc:annotation-driven/> 的前面(上面),否则配置不会生效
需要jackson的依赖
<dependency> <groupId>com.fasterxml.jackson.core</groupId> <artifactId>jackson-databind</artifactId> <version>2.8.8</version> </dependency>
如果上面这个不够,那就再追加或者替换为:
<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>
