5.当spring容器启动的时候,自动把实现了ApplicationContextAware的类找出来，然后为其注入ApplicationContext属性，使得SpringContextUtil可以自由自在的根据名字获取Bean实例。当需要手动获取Bean实例时，就可以直接使用工具类来获取。

6.项目中常用的数据类型转换中，工具类JsonToBeanUtil.java提供了json和bean相互转换的方法，主要支持gson和fastjson。

    }

12.业务逻辑描述：在工单系统的详情页中，需要展示对工单的操作记录，所以做了通用的模块设计，这样当要对工单详情中的日志部分作出修改的时候，能在最短的时间，最小的改动的情况下，完美的解决问题。日志表中新增附件字段，关联app_attachment表中的主键，当操作人与登录人相一致时，可以通过附件上传文件。

　　解决方案：抽象出了详情页面中的orderOptList.vm模块，在工单详情页中通过$control.setTemplate("web:orderOptList.vm")引入到工单详情页中，同时在后端需要提供公共的context.put("operations", operations)和context.put("appUserInfo", pvgInfo)来配合前端数据的展现。

2.业务逻辑描述：需要在工单的详情页中添加是否超时字段，用于在结单时判断工单是否超时，如果逐个在工单中添加，侵入式太重，不利于后期维护，因此利用了java的反射机制，动态的更新是否超时字段。

　　解决方案：方法中的参数设置为超级父类Object，传入的类，通过.getClass().getDeclaredMethod("方法名"，方法入参逗号分隔)获取到Method类，然后再满足业务逻辑的情况下，通过method.invoke(Object obj, Object.. args)方法，调用方法刷新数据。

反射代码

对类的方法实现动态赋值，使用方法method.invoke(obj,args...)方法，方法中的obj就是一个实例化对象，args是方法的参数。

public Object invoke(Object obj, Object... args)
    obj：从中调用底层方法的对象，必须是实例化对象
    args：用于方法调用，是一个object的数组，因为参数有可能有多个

3.业务逻辑描述：在内网系统中需要提供外网访问的API接口的时候，需要

　　解决方案：

4.业务逻辑描述：对部门敏感数据采用md5进行加密。

附：

1.解决SVN冲突心得：Eclipse分支调整顺序提交一次，复制到冲突分之中，复制提交一次，然后合并代码发布就可以了。
