Question

我拼命想要将1.4.0.RC1 spring-data-mongo移除到至少1.4.0.RELEASE的春季数据....

我现在遇到的问题是：

我们在域对象中使用String作为@id字段

public class AbstractDocument implements Identifiable<String> {

@Id
@Indexed(unique = true, background = true)
private String id;

public AbstractDocument() {
    id = UUID.randomUUID().toString();
}
@Override
public String getId() {
    return id;
}

public void setId(String id) {
    this.id = id;
}

}

所以，这里没什么特别的，但是我觉得这很奇怪＆＃34;无法将java.lang.String字段AbstractDocument.id设置为java.lang.Integer＆＃34; 错误，我尝试提供一个带有整数输入的setter，但没有任何变化，任何建议我在这里做错了以及我如何规避它？！

这很奇怪，因为在数据库中只是string-id字段：/而且太糟糕了这只发生在从RC1更新（不应该在第一时间使用，肯定）到相同版本的RELEASE;（< / p>
