我已经使用Google端点创建了一个方法并将其公开.我想要的只是从Google DataStore保存和检索数据.
当我尝试使用API Explorer进行测试时,出现以下错误 –
java.lang.NoSuchMethodError
我已附上以下代码
@ApiMethod (name ="mTest")
public void mTest(@com.google.api.server.spi.config.Named("UName") String UName) throws IOException {
DatastoreService datastoreService;
datastoreService = DatastoreServiceFactory.getDatastoreService();
Transaction tx=datastoreService.beginTransaction();
try {
Key userKey = KeyFactory.createKey("USERS_PK",UName);
Entity userEntity=new Entity("M_USERS",userKey);
userEntity.setProperty("TestColumn","TestColumnValue");
datastoreService.put(userEntity);
tx.commit();
}finally {
if (tx.isActive()){
tx.rollback();
}
}
}
在datastoreService.put(userEntity)上遇到错误;
请在下面找到堆栈跟踪：
