【spring mvc】 用spring mvc 报错406解决

1.spring mvc  使用 @responsebody 生成json需要依赖jackson的jar包

    maven 依赖

 <properties>      <jackson.version>2.3.3</jackson.version>      <jackson-mapper.version>1.9.13</jackson-mapper.version>  </properties> <dependencies><!-- Spring MVC 生成JSON的实现 -->      <dependency>          <groupId>com.fasterxml.jackson.core</groupId>          <artifactId>jackson-databind</artifactId>          <version>${jackson.version}</version>      </dependency>      <dependency>          <groupId>com.fasterxml.jackson.core</groupId>          <artifactId>jackson-annotations</artifactId>          <version>${jackson.version}</version>      </dependency>      <dependency>          <groupId>com.fasterxml.jackson.core</groupId>          <artifactId>jackson-core</artifactId>          <version>${jackson.version}</version>      </dependency>      <dependency>          <groupId>org.codehaus.jackson</groupId>          <artifactId>jackson-mapper-lgpl</artifactId>          <version>${jackson-mapper.version}</version>      </dependency></dependencies>
