Summary of sping and SSH configuration __web development in Java Web development

1. The birth of spring

In order to solve the complex structure of large enterprise application, it involves many external resources, transaction density, large data scale, many users, strong security considerations and higher performance requirements. ------Rod Jonson (author of Spring)

2. Spring optimization

Spring is part of the integration framework, whose core is based on control reversals (inverse, the IOC), and Spring is a comprehensive solution: it advocates not reinventing the wheel.

3, the module that spring contains

Core, AOP, DAO, ORM, JEE, WEB.

4. Spring's core mechanism----dependency Injection

The so-called dependency injection is that when a role requires assistance from another role, it is usually the caller who creates the instance of the callee. In spring, the work of the creator invoking the instance is often done by the spring container and then injected to the caller.

For example, an object that requires service in action, we can use injection to implement the object's reference.

Private UserService UserService;

Public void setuserservice (UserService userservice) {

this. UserService = UserService;

}

5. log4j Logging-----log4j.properties

"Norms:

#ootLogger是所有日志的根志, modifying this log property will work on all logs

#有日志的输出级别info, Output source console

#log4j. Rootlogger=info,console

#定义输出位置是控制台

Log4j.appender.console=org.apache.log4j.consoleappender

#日志布局采用的类

Log4j.appender.console.layout=org.apache.log4j.patternlayout

#日志输出布局

log4j.appender.console.conversionpattern= [%p]%d{yyyy-mm-dd

HH:MM:SS}%m%l

"" Practical:

Log4j.rootlogger=debug,console,file

Log4j.appender.console=org.apache.log4j.consoleappender

Log4j.appender.console.layout=org.apache.log4j.patternlayout

log4j.appender.console.conversionpattern= [%p]%d{yyyy-mm-dd HH:mm:ss}%m%l

Log4j.appender.file=org.apache.log4j.fileappender

Log4j.appender.file.file=${log4j_root}/logs.file

Log4j.appender.file.layout=org.apache.log4j.patternlayout

Log4j.appender.file.layout.conversionpattern=[%p]%d{yyyy-mm-dd HH:mm:ss}%m%r%n

6, SSH integration

(1) Construction of SSH framework

Steps:

1, add all the integrated jar package.

2, add order struts2,hibernate3,spring2.5 or Spring3.0.

3, respectively, the configuration of Web.xml, Hibernate, Dao.xml, Srvice.xml, Action.xml and Applicationcontent.xml

Main configuration under Web.xml file:

<!--configuration Spring-->

<context-param>

<param-name>contextConfigLocation</param-name>
