SpringMVC @ResponseBody 415错误处理

SpringMVC @ResponseBody 415错误处理：

解决方案：

（1）添加springMVC需要添加如下配置。（注意spring版本，3.x和4.x配置不同）
spring3.x是org.springframework.http.converter.json.MappingJacksonHttpMessageConverter

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

spring4.x是org.springframework.http.converter.json.MappingJackson2HttpMessageConverter

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

(2)pom.xml添加jackson依赖（这个要注意spring版本，3.x和4.x配置不同）

spring3.x:

 <dependency>
            <groupId>org.codehaus.jackson</groupId>
            <artifactId>jackson-core-lgpl</artifactId>
            <version>1.8.1</version>
         </dependency>
 
 
        <dependency>
            <groupId>org.codehaus.jackson</groupId>
            <artifactId>jackson-mapper-lgpl</artifactId>
            <version>1.8.1</version>
        </dependency>

spring4.x:

	    <dependency>
			<groupId>com.fasterxml.jackson.core</groupId>
			<artifactId>jackson-core</artifactId>
			<version>2.5.2</version>
		</dependency>
		
		<dependency>
			<groupId>com.fasterxml.jackson.core</groupId>
			<artifactId>jackson-databind</artifactId>
			<version>2.5.2</version>
		</dependency>
