在pom文件中添加下面三种依赖jar包

<dependency> <groupId>com.fasterxml.jackson.core</groupId> <artifactId>jackson-annotations</artifactId> <version>2.9.8</version> </dependency> <dependency> <groupId>com.fasterxml.jackson.core</groupId> <artifactId>jackson-core</artifactId> <version>2.9.8</version> </dependency> <dependency> <groupId>com.fasterxml.jackson.core</groupId> <artifactId>jackson-databind</artifactId> <version>2.9.8</version> </dependency>

spring.xml中加入以下bean

<bean class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter"> <property name="messageConverters"> <list> <ref bean="mappingJacksonHttpMessageConverter" /> </list> </property> </bean> <bean id="mappingJacksonHttpMessageConverter" class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter"> <property name = "supportedMediaTypes"> <list> <bean class="org.springframework.http.MediaType"> <constructor-arg index="0" value="text"/> <constructor-arg index="1" value="plain"/> <constructor-arg index="2" value="UTF-8"/> </bean> <bean class="org.springframework.http.MediaType"> <constructor-arg index="0" value="*"/> <constructor-arg index="1" value="*"/> <constructor-arg index="2" value="UTF-8"/> </bean> <bean class="org.springframework.http.MediaType"> <constructor-arg index="0" value="text"/> <constructor-arg index="1" value="*"/> <constructor-arg index="2" value="UTF-8"/> </bean> <bean class="org.springframework.http.MediaType"> <constructor-arg index="0" value="application"/> <constructor-arg index="1" value="json"/> <constructor-arg index="2" value="UTF-8"/> </bean> </list> </property> </bean>
