Spring+Struts2+IBatis 项目整合(一)

本文以简单人事管理系统为基础.介绍手动方式配置Spring+Struts2+Ibatis的项目基本框架

 

 

首先,用MyEclipse 新建一个web project

 

一.Ibatis

先是Ibatis的配置:

 1.把ibatis-2.3.4.726.jar复制到项目的WEB-INFO/lib下 刷新eclipse

 2.建立ibatis的包,在此 我创建了 com.dbke.hrms.ibatis.map包.

 3.在包中新建一个 dept.xml 内容如下:

 

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE sqlMap PUBLIC "-//ibatis.apache.org//DTD SQL Map 2.0//EN"
    "http://ibatis.apache.org/dtd/sql-map-2.dtd">

<sqlMap namespace="deptEntity">
	<typeAlias alias="employee"
		type="com.dbke.hrms.ibatis.domain.TEmployee" />
	<typeAlias alias="dept" type="com.dbke.hrms.ibatis.domain.TDept" />
	
	<resultMap id="get-dept-result" class="dept">
	<result property="IDeptId" column="DEPTID" jdbcType="int" javaType="java.lang.Integer" />
	<result property="vcDeptCode" column="DEPTCODE" jdbcType="VARCHAR(30)" javaType="java.lang.String" />
	<result property="vcDeptName" column="DEPTNAME" jdbcType="VARCHAR(10)" javaType="java.lang.String" />
	<result property="vcDeptAddress" column="ADDRESS" jdbcType="VARCHAR(50)" javaType="java.lang.String" />
	<result property="vcDeptTelphone" column="TELPHONE" jdbcType="VARCHAR(20)" javaType="java.lang.String" />
	<result property="vcDeptDesc" column="DESC" jdbcType="VARCHAR(255)" javaType="java.lang.String" />
	<result property="employees" column="DEPTID" select="findEmpByDeptId" />
	</resultMap>
	
	<parameterMap id="insert-dept-full-paramter" class="dept" >
		<parameter property="IDeptId" jdbcType="int"/>
		<parameter property="vcDeptCode" jdbcType="VARCHAR(30)"/>
		<parameter property="vcDeptName" jdbcType="VARCHAR(10)"/>
		<parameter property="vcDeptAddress" jdbcType="VARCHAR(50)"/>
		<parameter property="vcDeptTelphone" jdbcType="VARCHAR(20)"/>
		<parameter property="vcDeptDesc" jdbcType="VARCHAR(255)"/>
	</parameterMap>
	
	<select id="findDeptById" parameterClass="int" resultMap="get-dept-result">
     	select * 
     	from T_DEPT as dept
     	<dynamic prepend="WHERE">
     		<isNotEmpty property="value">dept.DEPTID= #value#</isNotEmpty>   		
     	</dynamic> 
	</select>
	
	<select id="findEmpByDeptId" parameterClass="int"
		resultClass="employee">
		<![CDATA[
     	select emp.EMPID as IEmpId,emp.EMPNAME as vcEmpName,emp.GENDER as IEmpGender,emp.AGE 
       as IEmpAge ,emp.IDCARD as vcEmpIdCard,emp.PARTY as vcEmpParty,emp.SCHOOL 
       as vcEmpSchool,emp.MAJOR as vcEmpMajor,emp.TITLE as vcEmpTitle,emp.POST as vcEmpPost
     	from T_EMPLOYEE as emp  
     	where emp.DEPTID= #value#
      ]]>
	</select>
	
	<select id="findDeptByName" parameterClass="java.lang.String"
		resultMap="get-dept-result">
		select * 
     	from T_DEPT as dept
     	<dynamic prepend="WHERE">
     		<isNotEmpty property="value">dept.DEPTNAME= #value#</isNotEmpty>   		
     	</dynamic> 
	</select>
	
	<select id="findDeptByDeptCode" parameterClass="java.lang.String"
		resultMap="get-dept-result">
		select * 
     	from T_DEPT as dept
     	<dynamic prepend="WHERE">
     		<isNotEmpty property="value">dept.DEPTCODE= #value#</isNotEmpty>   		
     	</dynamic> 
	</select>
	
	<insert id="insertDept" parameterMap="insert-dept-full-paramter">
		insert into T_DEPT (
			DEPTID,DEPTCODE,DEPTNAME,ADDRESS,TELPHONE,`DESC`
		) values(
			?,?,?,?,?,?
		)	
	</insert>
</sqlMap>

 4.建立包 com.dbke.hrms.ibatis.domain 并建立PO类 TDept.java :

 

package com.dbke.hrms.ibatis.domain;

import java.util.List;

public class TDept {

	private Integer IDeptId;		//部门ID
	
	private String vcDeptCode;		//部门编号
	
	private String vcDeptName;		//部门名称
	
	private String vcDeptAddress;		//部门地址
	
	private String vcDeptTelphone;		//部门电话
	
	private String vcDeptDesc;		//部门简介
	
	private List<TEmployee> employees;	//部门所属员工

	public Integer getIDeptId() {
		return IDeptId;
	}

	public void setIDeptId(Integer deptId) {
		IDeptId = deptId;
	}

	public String getVcDeptCode() {
		return vcDeptCode;
	}

	public void setVcDeptCode(String vcDeptCode) {
		this.vcDeptCode = vcDeptCode;
	}

	public String getVcDeptName() {
		return vcDeptName;
	}

	public void setVcDeptName(String vcDeptName) {
		this.vcDeptName = vcDeptName;
	}

	public String getVcDeptAddress() {
		return vcDeptAddress;
	}

	public void setVcDeptAddress(String vcDeptAddress) {
		this.vcDeptAddress = vcDeptAddress;
	}

	public String getVcDeptTelphone() {
		return vcDeptTelphone;
	}

	public void setVcDeptTelphone(String vcDeptTelphone) {
		this.vcDeptTelphone = vcDeptTelphone;
	}

	public String getVcDeptDesc() {
		return vcDeptDesc;
	}

	public void setVcDeptDesc(String vcDeptDesc) {
		this.vcDeptDesc = vcDeptDesc;
	}

	public List<TEmployee> getEmployees() {
		return employees;
	}

	public void setEmployees(List<TEmployee> employees) {
		this.employees = employees;
	}
	
	
}

 

5.创建 com.dbke.hrms.ibatis.dao 并创建 数据库dao接口 TDeptDao.java:

 

package com.dbke.hrms.ibatis.dao;

import java.util.List;

import com.dbke.hrms.ibatis.domain.TDept;

public interface TDeptDao {
	
	/**
	 * 查找所有的部门
	 * @return
	 */
	public List<TDept> findAllDept();
	
	/**
	 * 根据部门Id 查找特定部门
	 * @param deptId
	 * @return
	 */
	public TDept findDeptById(Integer deptId);
	
	/**
	 * 根据部门名称 查找特定部门
	 * @param deptName
	 * @return
	 */
	public TDept findDeptByName(String deptName);
	
	/**
	 * 根据部门编号 查找特定部门
	 * @param deptCode
	 * @return
	 */
	public TDept findDeptByCode(String deptCode);
	
	/**
	 * 新插入一个部门
	 * @param dept
	 * @return
	 */
	public Integer insertDept(TDept dept);
	
}

 6.在com.dbke.hrms.ibatis.dao.impl 实现这个接口,TDeptDaoImpl.java:

 

package com.dbke.hrms.ibatis.dao.impl;

import java.util.List;

import com.dbke.hrms.ibatis.dao.TDeptDao;
import com.dbke.hrms.ibatis.domain.TDept;

import org.springframework.dao.DataAccessException;
import org.springframework.orm.ibatis.support.SqlMapClientDaoSupport;

public class TDeptDaoImpl extends SqlMapClientDaoSupport implements TDeptDao {

	@SuppressWarnings("unchecked")
	@Override
	public List<TDept> findAllDept() {
		// TODO Auto-generated method stub
		return (List<TDept>)getSqlMapClientTemplate().queryForList("findDeptById");
	}

	@Override
	public TDept findDeptById(Integer deptId) throws DataAccessException {
		// TODO Auto-generated method stub
		return (TDept)getSqlMapClientTemplate().queryForObject("findDeptById",deptId);
	}

	@Override
	public Integer insertDept(TDept dept) {
		// TODO Auto-generated method stub
			return (Integer)getSqlMapClientTemplate().insert("insertDept", dept);
	}

	@Override
	public TDept findDeptByName(String deptName) {
		// TODO Auto-generated method stub
		return (TDept)getSqlMapClientTemplate().queryForObject("findDeptByName",deptName);
	}

	@Override
	public TDept findDeptByCode(String deptCode) {
		// TODO Auto-generated method stub
		return (TDept)getSqlMapClientTemplate().queryForObject("findDeptByDeptCode",deptCode);
	}
	

}

org.apache.commons.dbcp.BasicDataSource

你确定依赖库是放正确了的?
没有冲突?

你可以参照我发上去的依赖库清单 试一试

哈哈，老子找到你的blog了哈！！！没得办法我到处找关于异常
