java工程调试如何定位到调用者(基础问题)?
在注册完用户，邮箱验证后，执行一次update修改用户状态就可以了，找不到哪里执行了delete操作，导致用户信息没有了。所以把user.xml里的delete部分删除了（如下），控制台提示如下。
问题：如何通过提示定位到调用delete的代码？
1.user.xml
<delete id="delete"> delete from user where email=#{email}
</delete>
2.控制台部分输出：

修改用户状态
public boolean enable(String key) {String email = registerCache.getIfPresent(key);
if(StringUtils.isBlank(email)) {
return false;
}
User updateUser = new User();
updateUser.setEmail(email);
updateUser.setEnable(1);
userMapper.update(updateUser);
registerCache.invalidate(key);
return true;
}
4.缓存相关
private final Cache<String, String> registerCache = CacheBuilder.newBuilder().maximumSize(100) .expireAfterAccess(15, TimeUnit.MINUTES)
.removalListener(new RemovalListener<String, String>() {
@Override
public void onRemoval(RemovalNotification<String, String> notification) {
userMapper.delete(notification.getValue());
}
}).build();
回答：
enable里面 registerCache.invalidate(key);将该缓存置为无效(移除)。缓存中有个removalListener监听，当移除缓存时，回调onRemoval，然后执行userMapper.delete
