Java Web开发 SSH配置文件案例详解（eclipse开发自存）

本文并没有具体的Dao，Service，Action代码实现，知识分享了下SSH整合框架中 那些配置文件的模板，仅供参考，有不对的地方欢迎大家指正

简单实例：实体类Departmentinfo 与 Employeeinfo 如下

package com.prj.bean;

import java.util.HashSet;
import java.util.Set;

/**
 * Departmentinfo entity. @author MyEclipse Persistence Tools
 */

public class Departmentinfo implements java.io.Serializable {

    // Fields

    private Integer departmentId;
    private String departmentName;
    private Set employeeinfos = new HashSet(0);

    // Constructors

    /** default constructor */
    public Departmentinfo() {
    }

    /** full constructor */
    public Departmentinfo(String departmentName, Set employeeinfos) {
        this.departmentName = departmentName;
        this.employeeinfos = employeeinfos;
    }

    // Property accessors

    public Integer getDepartmentId() {
        return this.departmentId;
    }

    public void setDepartmentId(Integer departmentId) {
        this.departmentId = departmentId;
    }

    public String getDepartmentName() {
        return this.departmentName;
    }

    public void setDepartmentName(String departmentName) {
        this.departmentName = departmentName;
    }

    public Set getEmployeeinfos() {
        return this.employeeinfos;
    }

    public void setEmployeeinfos(Set employeeinfos) {
        this.employeeinfos = employeeinfos;
    }

}

package com.prj.bean;

import java.sql.Timestamp;

/**
 * Employeeinfo entity. @author MyEclipse Persistence Tools
 */

public class Employeeinfo implements java.io.Serializable {

    // Fields

    private Integer employeeNo;
    private Departmentinfo departmentinfo;
    private String employeeName;
    private String job;
    private Double salary;
    private Timestamp birthday;

    // Constructors

    /** default constructor */
    public Employeeinfo() {
    }

    /** full constructor */
    public Employeeinfo(Departmentinfo departmentinfo, String employeeName,
            String job, Double salary, Timestamp birthday) {
        this.departmentinfo = departmentinfo;
        this.employeeName = employeeName;
        this.job = job;
        this.salary = salary;
        this.birthday = birthday;
    }

    // Property accessors

    public Integer getEmployeeNo() {
        return this.employeeNo;
    }

    public void setEmployeeNo(Integer employeeNo) {
        this.employeeNo = employeeNo;
    }

    public Departmentinfo getDepartmentinfo() {
        return this.departmentinfo;
    }

    public void setDepartmentinfo(Departmentinfo departmentinfo) {
        this.departmentinfo = departmentinfo;
    }

    public String getEmployeeName() {
        return this.employeeName;
    }

    public void setEmployeeName(String employeeName) {
        this.employeeName = employeeName;
    }

    public String getJob() {
        return this.job;
    }

    public void setJob(String job) {
        this.job = job;
    }

    public Double getSalary() {
        return this.salary;
    }

    public void setSalary(Double salary) {
        this.salary = salary;
    }

    public Timestamp getBirthday() {
        return this.birthday;
    }

    public void setBirthday(Timestamp birthday) {
        this.birthday = birthday;
    }

}
