ERROR - Exception executing batch: 
org.hibernate.StaleStateException: Batch update returned unexpected row count fr
om update [0]; actual row count: 0; expected: 1

ERROR - Could not synchronize database state with session
org.hibernate.StaleStateException: Batch update returned unexpected row count fr
om update [0]; actual row count: 0; expected: 1


不注意的话，还真的有点无所适从，Batch update returned unexpected row count from update [0]; actual row count: 0; expected: 1
这个异常是由于主键设置为自增长，而在我们插入记录的时候设置了ID的值导致的。看下我的Hibernate映射文件中ID的定义：

在使用Arrays.asList()后调用add，remove这些method时出 现java.lang.UnsupportedOperationException异常。这是由于Arrays.asList() 返回java.util.Arrays$ArrayList， 而不是ArrayList。Arrays$ArrayList和ArrayList都是继承AbstractList，remove，add等 method在AbstractList中是默认throw UnsupportedOperationException而且不作任何操作。ArrayList override这些method来对list进行操作，但是Arrays$ArrayList没有override remove()，add()等，所以throw UnsupportedOperationException。
例如：

String[] s = {
"one", "two", "three", "four", "five",
"six", "seven", "eight", "nine", "ten",
};

List a = Arrays.asList(s);

解决办法：List b = new ArrayList(a);然后再去执行add和remove；

    此异常是由于Spring提供的Open Session In View而引起的。
    开启OpenSessionInViewFilter这个过滤器的时候FlushMode就已经被默认设置为了MANUAL，如果FlushMode是MANUAL或NEVEL,在操作过程中 hibernate会将事务设置为readonly，所以在增加、删除或修改操作过程中会出现该错误

http://jayenho.blog.51cto.com/37194/91556
原因：数据库down掉了，或者网络断了，连接connection无效，未验证，抛出此异常。当数据库连接因为某种原因断掉（有可能时网络问题，导致App Server跑了一天后，第二天再跑马上爆错误），再从Connection Pool中获取连接而又不做Validate，这时候取得的Connection实际上已经是无效的了，从而导致程序一跑，马上爆Connect Reset错误。
在Tomcat的Server.xml中添加_testOnBorrow，_testOnReturn，_testWhileIdle，并且都设置为true，同时
validationQuery添加验证语句可避免“Connection Reset”error。
