springmvc接口接收json类型参数设置
Springmvc需要如下配置：
1.开启注解
<!-- 开启注解--> <mvc:annotation-driven />
2.加入相关bean
<bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">
<property name="messageConverters">
<list>
<ref bean="jsonHttpMessageConverter" />
</list>
</property>
</bean>
<bean >
<property name="supportedMediaTypes">
<list>
<value>application/json;charset=UTF-8</value>
</list>
</property>
</bean>
3.maven加入jackson依赖
<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>
4.controller层入参要加注解@RequestBody
