  1、在pom文件中需引入
  

  <dependency>
    <groupId>com.fasterxml.jackson.core</groupId>
    <artifactId>jackson-databind</artifactId>
    <version>2.9.6</version>
  </dependency>

  2、在applicationContext.xml配置文件中引入即可。

  <mvc:annotation-driven>
      <mvc:message-converters>
          <bean class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter"></bean>
      </mvc:message-converters>
  </mvc:annotation-driven>

  我来：如果你的依赖的SpringMVC的包版本是4.0.9以上的，那么就不能用视屏中的jackson.jar  依赖用这三个:

  <dependency>

      <groupId>com.fasterxml.jackson.core</groupId>

      <artifactId>jackson-databind</artifactId>

      <version>2.5.0</version>

  </dependency>

  <dependency>

      <groupId>com.fasterxml.jackson.core</groupId>

      <artifactId>jackson-core</artifactId>

      <version>2.5.0</version>

  </dependency>

  <dependency>

      <groupId>com.fasterxml.jackson.core</groupId>

      <artifactId>jackson-annotations</artifactId>

      <version>2.5.0</version>

  </dependency>

  1. spring mvc有沒有配置<mvc:annotation-driven/>

  2. 是不是json包沒有正確引入jackson-annotations-2.x.jar /jackson-core-2.x.jar/jackson-databind-2.x.jar
