Maven搭建Struts2 Spring Hibernate4框架

  Struts2版本 2.3.24,Spring版本4.0.4.RELEASE,Hibernate版本4..2.3.Final。搭建之前刻意查看了下自己电脑下载好的jar包,不用maven的时候就是用这些版本,估计用maven也不会出错,就用这个了。

1:pom.xml: 

  1)Struts2:

  struts2-core:Struts2的核心jar包;

  struts2-convention-plugin:convention-plugin插件,使用了这个插件之后,就可以采用注解的方式配置Action,虽然我不大爱用注解吧。

  struts2-config-browser-plugin:config-browser-plugin插件,使用了这个插件之后,就可以很方便的浏览项目中的所有action及其与 jsp view的映射。http://localhost:8080/SSH/config-browser/actionNames.action,SSH为项目名。

  struts2-spring-plugin:Struts2和Spring整合插件 ,这个一定要有。

  2)Spring:

  spring-core:Spring的核心jar包

  spring-context:上下文jar包

  spring-jdbc:连接jdbc的jar包,一般在获取dataSource时使用。

  spring-beans:很明显,beans的jar包,必须有

  spring-web:web的jar包,没想到在哪用了,我又没用spring mvc。

  spring-expression:这个是表达式的。

  spring-orm:orm对象关系映射,和hibernate有关,这个很重要。不同于struts2与spring整合需要struts2-spring-plugin,spring-orm就是spring和hibernate的整合。

  3)Hibernate:

  hibernate-core:hibernate和核心jar包

  4)MySQL: 

  mysql-connector-java:我连接的是mysql数据库,网上说要是连接oracle,需要把jar包下载到本地仓库,用maven不会下载oracle的jar包,具体怎么配置maven的本地仓库我是忘记了,不过我记得我的本地仓库在哪。

  5)C3P0数据库连接池

  c3p0:hibernate就是用的这个数据库连接池,所以我显式的用c3p0来配置dataSource

  6)Aspectj

  aspectjweaver:跟事务那里有关,有个织入的过程,这个可以看spring的事务管理

  7)javax.servlet

  javax.servlet-api:没它项目必然报错

  8)junit

  junit:单元测试

2:web.xml

  1)Spring:

  在这里配置spring的监听器,配置文件的位置,不需要配置spring的servlet,页面流用struts2

  2)openSessionInViewFilter

  还不大懂,后续再补充

  3)Struts2:

  配置Struts2的核心过滤器

3:struts.xml

  Sturts2的配置文件,初步一看内容挺多,必须有的是package,没有包可不行。

DynamicMethodInvocation也得有,后面用到时会说这个。

  spring-beans.xml是用来配置spring用到的bean的,spring-hibernate是spring和hibernate的整合。

  至此,配置文件什么的,差不多是完成了,现在看下目录结构

6:代码

  

  1)com.zhao.entity是实体类,里面有Student类和其对应的对象关系映射文件,Student类里写了好几个构造方法,是为了测试方便,其实没必要写这么多。

package com.zhao.entity;

import java.io.Serializable;

public class Student implements Serializable {
    private Integer stu_id;
    private String stu_name;
    private String stu_gender;

    public Student() {
    }

    public Student(Integer stu_id, String stu_name, String stu_gender) {
        this.stu_id = stu_id;
        this.stu_name = stu_name;
        this.stu_gender = stu_gender;
    }

    public Student(String stu_name, String stu_gender) {
        this.stu_name = stu_name;
        this.stu_gender = stu_gender;
    }

    public Integer getStu_id() {
        return stu_id;
    }

    public void setStu_id(Integer stu_id) {
        this.stu_id = stu_id;
    }

    public String getStu_name() {
        return stu_name;
    }

    public void setStu_name(String stu_name) {
        this.stu_name = stu_name;
    }

    public String getStu_gender() {
        return stu_gender;
    }

    public void setStu_gender(String stu_gender) {
        this.stu_gender = stu_gender;
    }

    @Override
    public String toString() {
        return "Student [stu_id=" + stu_id + ", stu_name=" + stu_name + ", stu_gender=" + stu_gender + "]";
    }
}

            <column name="STU_GENDER" />
        </property>
    </class>
</hibernate-mapping>

  2)com.zhao.DAO和com.zhao.DAO.impl是数据库操作的接口包和实现类包,在具体的实现类中,要有对数据库的操作,所以自动装配sessionFactory。@Repository用于将数据访问层 (DAO 层 ) 的类标识为 Spring Bean,但是需要在 XML 配置文件中启用Bean 的自动扫描功能,这可以通过<context:component-scan/>实现,现在再看看spring-beans.xml,肯定能找到这句代码。

package com.zhao.DAO;

import java.io.Serializable;

import com.zhao.entity.Student;

public interface StudentDAO {
    public Serializable save(Student student);
}
package com.zhao.DAO.impl;

import java.io.Serializable;

import org.hibernate.SessionFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Repository;
import org.springframework.stereotype.Service;

import com.zhao.DAO.StudentDAO;
import com.zhao.entity.Student;

@Repository("studentDAO")
public class StudentDAOImpl implements StudentDAO{
    @Autowired
    private SessionFactory sessionFactory;

    @Override
    public Serializable save(Student student) {
        return sessionFactory.getCurrentSession().save(student);
    }

}

  3)com.zhao.Biz和com.zhao.Biz.impl是业务逻辑接口和其具体的实现类,@Service 通常作用在业务层,这里的注解和刚才数据库层的就不一样了。当然自动装配是肯定的。

package com.zhao.Biz;

import java.io.Serializable;

import com.zhao.entity.Student;

public interface StudentBiz {
    public Serializable save(Student student);
}
package com.zhao.Biz.impl;

import java.io.Serializable;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import com.zhao.Biz.StudentBiz;
import com.zhao.DAO.StudentDAO;
import com.zhao.entity.Student;

@Service("studentBiz")
public class StudentBizImpl implements StudentBiz {
    @Autowired
    private StudentDAO studentDAO;

    @Override
    public Serializable save(Student student) {
        return studentDAO.save(student);
    }

}

  4)com.zhao.action里面是struts2的action,这里用的是注解,倒没觉得有什么好,没有struts.xml看的清楚。action肯定要有package,还要有命名空间namespace。具体页面跳转,逻辑视图怎么找到物理视图资源,过几天再整理。ModelDriver<Student>模型驱动的形式获取了页面提交的数据,看来近期有必要整理下struts2获取数据的几种方式了。

package com.zhao.action;

import org.apache.struts2.convention.annotation.Action;
import org.apache.struts2.convention.annotation.Namespace;
import org.apache.struts2.convention.annotation.ParentPackage;
import org.springframework.beans.factory.annotation.Autowired;

import com.opensymphony.xwork2.ActionSupport;
import com.opensymphony.xwork2.ModelDriven;
import com.zhao.Biz.StudentBiz;
import com.zhao.DAO.StudentDAO;
import com.zhao.entity.Student;

@ParentPackage("default")
@Action(value="login")
@Namespace("/")
public class LoginAction extends ActionSupport implements ModelDriven<Student> {
    @Autowired
    private StudentBiz biz;

    private Student student = new Student();

    public String login() throws Exception {
        System.out.println(biz.save(student));
        System.out.println(student);
        return "login";
    }

    @Override
    public Student getModel() {
        if (student == null) {
            student = new Student();
        }
        return student;
    }
}

  5)前端页面,index.jsp中input的name和Student实体类中的属性名是一样的,注意看我们表单的action:"login!login.action",以.action结尾是因为我们定义的struts2默认拦截.action结尾的请求,无论是在web.xml还是struts.xml我们都是这么配置的,!之前是指向action的,在com.zhao.action.LoginAction中配置了这个名字,看LoginAction,有注解@Action,里面的value就是这个值,如果没配置value,默认就是类名删去Action的那部分,当然 也是login。!之后是我们在这个Action里具体用哪个方法,也就是我们的方法名,如果想用这种方式动态的指定方法,而不是用默认的execute()方法的话,必须在struts.xml中配置动态方法调用,也就是struts.enable.DynamicMethodInvocation为true,这个单词的意思就是动态方法调用。在WEB-INF的content目录下还有login.jsp,这个名字跟上面那个action返回的String是一样的。

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Login Page</title>
</head>
<body>    
    <form action="login!login.action" method="post">
        Name: <input type="text" name="stu_name"/>
        <br/>
        Password: <input type="password" name="stu_password"/>
        <br/>
        <input type="submit" value="Submit"/>
    </form>
</body>
</html>
<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Insert title here</title>
</head>
<body>
    搭建成功
</body>
</html>

接下来看看效果

7:效果

看来这个动态方法调用没那么好用,上面那个URL太可怕了,近期得把它改改。

  数字6是保存到数据库中自动增长的主键值,Serializable。

  至于单元测试什么的,写代码的时候写了,这里就不写了。至此,告一段落。
