一, 通过IDE创建项目, 并创建相应的包结构

查看web.xml中的StrutsPrepareAndExecuteFilter包名是否正确.不正确的话去掉.ng包.

二 整合Hibernate到Spring中

右键数据库, 创建表

如果遇到如下问题:

解决方法:

手动创建一个sessionFactory
此时选项中便有了可选项

自动生成如下内容

导入需要的jdbc驱动包后修改配置如下:
com.minicuper.ssh.entity.UserEntity
jdbc:mysql://localhost:3306/ssh
com.mysql.jdbc.Driver
root
1234
thread
true
true
org.hibernate.dialect.MySQL5Dialect
create
生成的实体类中有一些错误

解决方法:为sessionFactory指定对应的DataSources即可

三 整合Struts到Spring中.
配置ContextLoaderListener, 使WebApp启动时便初始化Spring配置文件
ContextLoaderListener类在spring-web.jar包中.需要手动引入jar包.
web.xml
struts2
org.apache.struts2.dispatcher.filter.StrutsPrepareAndExecuteFilter
struts2
/*
org.springframework.web.context.ContextLoaderListener
contextConfigLocation
classpath:spring-config.xml
创建的类,及修改的类 :

this.userService = userService;

System.out.println("UserAction regist()");
if(userService.regist(user)){
result = "注册成功";
return SUCCESS;
}else {

常见问题:
- sessionFactory.getCurrentSession()
异常: org.hibernate.HibernateException: Could not obtain transaction-synchronized Session for current thread
配置不起作用:thread
解决方法: 配置HibernateTransactionManager
在Spring配置文件中添加:
后在Service类上添加注解:@Transactional
- 配置事务时
出现异常:org.hibernate.service.UnknownUnwrapTypeException: Cannot unwrap to requested type [javax.sql.DataSource]
解决方法:
1.导入c3p0相关的包.
2.修改spring.config.xml
3.Dao类中原来的事务操作删掉即可

- 配置c3p0时: 出现 ClassNotFoundException: com.mchange.v2.ser.Indirector
解决方法:添加 mchange-commons-java.jar包
