我ToStringBuilder.reflectionToString(class)在commons-lang中用来实现toString()简单的DTO.现在我正在尝试使用Google Guava而不是Apache commons库.我Objects.ToStringHelper在瓜瓦找到了.但如果班上有很多成员,那就太啰嗦了.例如:

@Override
public String toString() {
    return MoreObjects.toStringHelper(this.getClass()).add("name", name)
            .add("emailAddress", emailAddress)
            .add("department", department).add("yearJoined", yearJoined)
            .toString();
}

如果我使用commons-lang则更简单:

@Override
public String toString() {
    return ToStringBuilder.reflectionToString(this);
}

是否有更好的方法来实施toString()番石榴,而不是公共场所？

如何递归打印对象的内容？

我有一个巨大的对象,我当然有它的类,我从中提取一些值,但因为它真的很大,我不知道在哪个列表或我正在寻找的值是什么.

有没有办法创建某种对象分解路由并搜索每个部分的我期望的值,它隐藏在对象的某个地方,我只是在eclipse中找不到它太嵌套了.

我想过使用反射来遍历对象类的所有字段并搜索每个字段内的值(列表中的字段(列表列表等)).还有其他想法吗？

不幸的是,这些答案都没有帮助我,我正在开始赏金

我最近升级到Spring Security 4.2.3.RELEASE.我也在使用spymemcached v 2.8.4.我遇到了这种情况,由于某些原因,Spring正在尝试序列化服务实现类.我无法弄清楚这是从哪里来的.异常引用的代码行是

Set<Session> userSessions = (Set<Session>) memcachedClient.get(userId);
...
memcachedClient.set(userId, sessionTimeoutInSeconds.intValue(), userSessions); // dies here
