框架整合实例1-ssh

搭建用的框架：struts2 + Spring +Spring data jpa（这是Spring框架对hibernate二次包装）

配置文件：

web.xml
Struts2框架   src/struts.xml，空文件即可。
~~Hibernate框架~~   src/hibernate.cfg.xml 在domain有 Xxx.hbm.xml ，不需要这两个文件了。前者是配置连接数据库之类的信息，已经交给spring去管理，在applicationContext.xml中配置；后者是描述domain实体类和数据库表对应关系，这个直接在domain实体类中运用注解配置。
Spring框架   src/applicationContext.xml
关于日志   log4j.properties
关于数据库连接   db.properties

项目包结构：

用maven项目管理，导入依赖jar包

controller层

import com.opensymphony.xwork2.ActionSupport;
import com.opensymphony.xwork2.ModelDriven;

import org.apache.struts2.convention.annotation.Namespace;
import org.apache.struts2.convention.annotation.ParentPackage;
import org.apache.struts2.convention.annotation.Result;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Scope;
import org.springframework.stereotype.Controller;

/**

 */
@Namespace("/")
@ParentPackage("json-default")
@Controller
@Scope("prototype")
public class StudentAction extends ActionSupport implements ModelDriven<Student> {

    private Student student = new Student();

    @Override
    public Student getModel() {
        return student;
    }

    @Autowired
    private StudentService studentService;

    @Action(value = "addStudent", results = {@Result(name = "success", location = "./success.jsp", type = "redirect"), @Result(name = ERROR, location = "./error.jsp", type = "redirect")})
    public String addStudent() {

        studentService.addStudent(student);

        return SUCCESS;

    }

}

service层

package com.herbert.service;

import com.herbert.domain.Student;
/**
 * @author Herbert
 * @create 2019-06-09 15:55
 */
public interface StudentService {
    void addStudent(Student student);
}

package com.herbert.service;

import com.herbert.dao.StudentRepository;
import com.herbert.domain.Student;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;

/**

 */
@Service
@Transactional
public class StudentServiceImpl implements StudentService {

    @Autowired
    private StudentRepository studentRepository;

    @Override
    public void addStudent(Student student) {

        studentRepository.save(student);
    }
}

dao层

package com.herbert.dao;

import com.herbert.domain.Student;
import org.springframework.data.jpa.repository.JpaRepository;

/**
 * @author Herbert
 * @create 2019-06-09 15:58
 */
public interface StudentRepository extends JpaRepository<Student,Integer> {

}

访问路径：项目名 + namespace 的value值+ @action注解的value（访问路径可以不用带.action）

注意：controller层包结构一定要有一级带action结构，貌似struts2的源码哪块有规定这类格式

不然当你提交数据的时候，会报错
