解决问题参考两个地址:

前台:

$.ajax({
         type: "POST",
         contentType:"application/json", //加入这个
         url: "rest/approval/checkData",
         data: JSON.stringify(ds), //要变成字符串
         success: function(result){
           alert( "Data Saved: " + result.msg );
         }
      });

上面不解决问题情况下继续下面:

加入包:

<dependency>
                <groupId>com.fasterxml.jackson.core</groupId>
                <artifactId>jackson-databind</artifactId>
                <version>2.6.3</version>
            </dependency>
            <dependency>
                <groupId>com.fasterxml.jackson.core</groupId>
                <artifactId>jackson-core</artifactId>
                <version>2.6.3</version>
            </dependency>
            <dependency>
                <groupId>org.codehaus.jackson</groupId>
                <artifactId>jackson-mapper-asl</artifactId>

            </dependency>
            <dependency>
                <groupId>org.codehaus.jackson</groupId>

                <version>1.9.13</version>
            </dependency>

controller:

@RequestMapping(value = "/searchGrid.do", method= RequestMethod.POST, headers="Accept=application/json")
