我一直在努力配置谷歌应用引擎（gae）+泽西+ Maven。 我正在使用gae sdk 1.7.2，datanucleus-appengine 2.0.0.1和JDO 3.0。
我能够获得PersistenceManagerFactory但是在makePersistent时我得到了以下错误。
DataNucleus Enhancer（版本3.0.1）：使用ClassEnhancer“ASM”用于API“JDO”。

以下是我要坚持的课程：
@PersistenceCapable(identityType = IdentityType.APPLICATION)
public class User implements Serializable{
private static final long serialVersionUID = 1L;
@PrimaryKey
@Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
private Long id;
@Persistent
private String Name;
public User(){
}
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public String getName() {
return Name;
}
public void setName(String name) {
Name = name;
}
}
有人知道会导致该错误的原因吗？持久化阶段有什么问题吗？
答案 0 :(得分：1)
您认为NoSuchMethodError意味着什么？看看它的javadoc。某些方法在某些类中是预期的（即它被调用但它不存在。所以你搞砸了正在使用的（datanucleus-XXX）罐的版本.GAE JDO 3.0需要DataNucleus v3.0（并且没有v3。 1）但你正在拉一些v3.1 jar
