spring mvc用@requestbody 处理get请求

这个问题困扰我两天了。 我用springmvc  @requestbody 接收一个 用curl发的get请求，curl代码如下：curl -H "Content-type:application/json" -G -d "{\"backupAppBeansList\":[{\"id\":\"zzy5200122\",\"packageName\":\"zzy1\",\"label\":\"zzy2\",\"versionCode\":\"zzy2\",\"versionName\":\"zzy2\",\"backupTime\":20130905,\"operationType\":0,\"transactionId\":\"1234562\"},{\"id\":\"zzy5200122\",\"packageName\":\"zzy2\",\"label\":\"zzy2\",\"versionCode\":\"zzy2\",\"versionName\":\"zzy2\",\"backupTime\":20130905,\"operationType\":1,\"transactionId\":\"1234563\"},{\"id\":\"zzy5200122\",\"packageName\":\"zzy3\",\"label\":\"zzy2\",\"versionCode\":\"zzy2\",\"versionName\":\"zzy2\",\"backupTime\":20130905,\"operationType\":1,\"transactionId\":\"1234564\"}],\"backupFileBean\":{\"id\":\"123456\",\"phoneIMEI\":\"iphone4s\",\"appCount\":10,\"userId\":\"zzy520012\",\"backupTime\":20130904,\"phoneModel\":\"iphone\",\"backupType\":0}}" http://localhost:8080/NewAppBackup/Servlet/backup  不过 他总是报java.io.EOFException: No content to map to Object due to end of input at org.codehaus.jackson.map.ObjectMapper._initForReading(ObjectMapper.java:693) at org.codehaus.jackson.map.ObjectMapper._readMapAndClose(ObjectMapper.java:644) at org.codehaus.jackson.map.ObjectMapper.readValue(ObjectMapper.java:487)......这个错误。我如果发送和接收都改为post方式的话就完全没问题，但是我如果就想用get提交肿么办？不知道这个是哪里的问题.....有木有大神spring mvccurljson
