异常处理：No serializer found for class org.hibernate.proxy.pojo.javassist.JavassistLazyInitializer...org
遇到的原始异常信息是这样的：
org.codehaus.jackson.map.JsonMappingException: No serializer found for class org.hibernate.proxy.pojo.javassist.JavassistLazyInitializer and no properties discovered to create BeanSerializer (to avoid exception, disable SerializationConfig.Feature.FAIL_ON_EMPTY_BEANS) ) (through reference chain: dbaudit.dba.business.system.BusSystem_$$_javassist_32["handler"])

通过上网查询发现如下原因：
hibernate会给每个被管理的对象加上hibernateLazyInitializer属性，同时struts-jsonplugin或者其他的jsonplugin都是
因为jsonplugin用的是java的内审机制.hibernate会给被管理的pojo加入一个hibernateLazyInitializer属性,jsonplugin通过java的反射机制将pojo转换成json，会把hibernateLazyInitializer也拿出来操作,但是hibernateLazyInitializer无法由反射得到，所以就抛异常了。
所以在我的pojo类上加上如下声明：
@JsonIgnoreProperties(value={"hibernateLazyInitializer","handler","fieldHandler"})
如上图，会忽略其中的handler属性
@JsonIgnoreProperties(value={"hibernateLazyInitializer"}) （此时只是忽略hibernateLazyInitializer属性）要加载被lazy的，也就是many-to-one的one端的pojo上
这行代码的作用在于告诉你的jsonplug组件，在将你的代理对象转换为json对象时，忽略value对应的数组中的属性，即：
通过java的反射机制将pojo转换成json的，属性，(通过java的反射机制将pojo转换成json的，)
"hibernateLazyInitializer","handler","fieldHandler",（如果你想在转换的时候继续忽略其他属性，可以在数组中继续加入）
