6       整合ssh架構

6.1     依賴傳遞

隻添加了一個struts2-core依賴，發現項目中出現了很多jar，

這種情況 叫 依賴傳遞

maven學習記錄三——maven整合ssh架構6       整合ssh架構7      分子產品開發

6.2     依賴版本沖突的解決

1、  第一聲明優先原則

<dependencies>

  <!--   spring-beans-4.2.4 -->

       <dependency>

                 <groupId>org.springframework</groupId>

                 <artifactId>spring-context</artifactId>

                 <version>4.2.4.RELEASE</version>
       </dependency>

<!--   spring-beans-3.0.5 -->

       <dependency>

                 <groupId>org.apache.struts</groupId>

                 <artifactId>struts2-spring-plugin</artifactId>

                 <version>2.3.24</version>

       </dependency>

2、  路徑近者優先原則

自己添加jar包

<dependency>

                 <groupId>org.springframework</groupId>

                 <artifactId>spring-beans</artifactId>

                 <version>4.2.4.RELEASE</version>

       </dependency> 

3、  排除原則

<dependency>
          <groupId>org.apache.struts</groupId>
          <artifactId>struts2-spring-plugin</artifactId>
          <version>2.3.24</version>
          <exclusions>
            <exclusion>
              <groupId>org.springframework</groupId>
              <artifactId>spring-beans</artifactId>
            </exclusion>
          </exclusions>
      </dependency>

4、  版本鎖定原則

<properties>

                   <spring.version>4.2.4.RELEASE</spring.version>

                   <hibernate.version>5.0.7.Final</hibernate.version>

                   <struts.version>2.3.24</struts.version>

         </properties>

 

         <!-- 鎖定版本，struts2-2.3.24、spring4.2.4、hibernate5.0.7 -->

         <dependencyManagement>

                   <dependencies>

                            <dependency>

                                     <groupId>org.springframework</groupId>

                                     <artifactId>spring-context</artifactId>

                                     <version>${spring.version}</version>

                            </dependency>

</dependencies>

</dependencyManagement>

需求：

傳客戶ID 頁面上顯示客戶資訊

準備資料庫

6.3     建構項目

1、  建立資料庫，

2、  執行準備好的sql腳本

3、  完善pom.xml檔案，把ssh相關的依賴都添加上去

                   </plugins>

         </build>

4、  完成實體類代碼

maven學習記錄三——maven整合ssh架構6       整合ssh架構7      分子產品開發

5、  完成dao代碼

接口

package cn.itcast.dao;

 

import cn.itcast.entity.Customer;

 

public interface CustomerDao {

        

         public Customer getById(Long id);

 

}

實作類

package com.itcast.dao.impl;

import org.springframework.orm.hibernate5.support.HibernateDaoSupport;

import cn.itcast.dao.CustomerDao;

import cn.itcast.entity.Customer;

public class CustomerDaoImpl extends HibernateDaoSupport implements CustomerDao {

         @Override

         public Customer getById(Long id) {

                   return this.getHibernateTemplate().get(Customer.class, id);

         }

}

6、  完成service代碼

接口

package com.itcast.service;

import cn.itcast.entity.Customer;

public interface CustomerService {

         public Customer getById(Long id);

} 

實作類

package com.itcast.service.impl;

 

import com.itcast.service.CustomerService;

 

import cn.itcast.dao.CustomerDao;

import cn.itcast.entity.Customer;

 

public class CustomerServiceImpl implements CustomerService {

         private CustomerDao  customerDao;

         public void setCustomerDao(CustomerDao customerDao) {

                   this.customerDao = customerDao;

         }

         @Override

         public Customer getById(Long id) {

                   return customerDao.getById(id);

         }

}

7、  完成action代碼

package cn.itcast.action;

import com.itcast.service.CustomerService;

import com.opensymphony.xwork2.ActionSupport;

import cn.itcast.entity.Customer;

public class CutomerAction extends ActionSupport {

         //兩個成員變量

         private Customer  customer;

        

         private Long custId;

         public Customer getCustomer() {

                   return customer;

         }

         public void setCustomer(Customer customer) {

                   this.customer = customer;

         }

         private CustomerService customerService;

         public void setCustomerService(CustomerService customerService) {

                   this.customerService = customerService;

         }

         public Long getCustId() {

                   return custId;

         }

         public void setCustId(Long custId) {

                   this.custId = custId;

         }

         public String findById(){

                   customer = customerService.getById(custId);

                   return SUCCESS;

         }

}

8、  拷貝配置檔案并修改

從如下圖位置拿到配置檔案

maven學習記錄三——maven整合ssh架構6       整合ssh架構7      分子產品開發

放入到 src/main/resources目錄中

maven學習記錄三——maven整合ssh架構6       整合ssh架構7      分子產品開發

修改内容 略

9、  修改web.xml 添加spring的監聽

<listener>

 <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>

</listener>

<context-param>

<param-name>contextConfigLocation</param-name>

<param-value>classpath:applicationContext.xml</param-value>

</context-param>        

10、              運作項目

7      分子產品開發

依賴範圍對依賴傳遞造成的影響（了解）

父工程來管理   聚合

7.1     建立父工程：

1、

maven學習記錄三——maven整合ssh架構6       整合ssh架構7      分子產品開發

2、建立出的父工程如下

maven學習記錄三——maven整合ssh架構6       整合ssh架構7      分子產品開發

3、在pom.Xml中添加以下資訊：
