Java EE环境相关笔记, basic introduction(JavaEE environment configuration，mysql introduction。)

　　1、Struts2框架下ActionSupport的使用（附加） 在Myeclipse中新建web项目lab4plus； 在实验四的基础上修改LoginAction，使之继承ActionSupport，并重写Validate方法，在其中增加FieldError、ActionError和ActionMessage； 修改login.jsp、loginSuccess.jsp和loginFail.jsp页面，用<s:actionmessage>和<s:actionerror>标签输出信息； 将lab4plus布署在Tomcat服务器上； 运行login.jsp页面，并记录运行结果、主要处理流程与关键代码。(, Struts2 framework ActionSupport use (additional) Create a new web project in Myeclipse lab4plus In the experiment on the basis of four modified LoginAction, so inheritance ActionSupport, and override the Validate method, in which the increase FieldError, ActionError and ActionMessage Modify login.jsp, loginSuccess.jsp and loginFail.jsp page with <s:actionmessage> and <s:actionerror> tag output information The lab4plus deployed on Tomcat server Run login.jsp page and record the results, the main processes and key code. )

Represents an evaluation of the goodness of a result.

介绍了SSH经典框架的运用，环境的搭建等一系列内容。为开发者提供了基础。(SSH classical framework introduced the use of environment to build a series of content. Provides developers with the foundation.)

技术要点： 1 此系统采用了目前最流行的ssm框架,其中的spingMVC框架相对于struts2框架更灵活，更安全。 2 本项目springMVC框架采用了注解映射器，使用了RESTful风格的url对系统发起http请求,开发更灵活。 3 同时使用了了hibernate提供的校验框架，对客户端数据进行校验！ 4 Mybati数据库DAO层采用的是Mapper代理开发方法，输入映射采用的是POJO包装类型实现,输出映射采用了resultMap类型，实现了数据库多对一映射。 5 spring容器内部使用拦截器，以Spring AOP的方式实现事务控制管理。(Technical points: 1. This system adopts the most popular SSM framework at present. The sping MVC framework is more flexible and safer than the struts 2 framework. 2 The spring MVC framework of this project adopts annotation mapper, and uses RESTful style URL to initiate HTTP requests to the system, which makes the development more flexible. 3 At the same time, the verification framework provided by hibernate is used to verify the client data.)

使用java编写的文件读取显示的软件，代码风格简洁便于读取，使用了java图形进行编写。可以用来功能拓展的二次开发，也可以用来入门学习java的图形化开发。(Prepared using the java file to read the display of the software, the code concise style is easy to read, the use of the java graphics to write. The two development can be used to extend functions, can also be used to the development of graphical java entry learning.)
