                </configuration>
            </plugin>
        </plugins>
    </build>
</project>

接着我喜欢从web端开始,所以先弄的是struts2

一个简单的action

package com.swift.web;

import com.opensymphony.xwork2.ActionSupport;
import com.swift.entity.Customer;
import com.swift.service.CustomerService;

public class CustomerAction extends ActionSupport {

    private Integer cid;
    private String name;
    private Customer cus;
    private CustomerService customerService;
    
    public void setName(String name) {
        this.name = name;
    }
    public void setCustomerService(CustomerService customerService) {
        this.customerService = customerService;
    }
    public Customer getCus() {
        return cus;
    }
    public void setCid(Integer cid) {
        this.cid = cid;
    }


    public String findById() throws Exception {
        
        cus=customerService.findById(cid);
        return "list";
    }
    public String add() throws Exception {
        
        Customer customer=new Customer();
        customer.setName(name);
        customerService.add(customer);
        return "index";
    }
}

配合struts.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts PUBLIC
    "-//Apache Software Foundation//DTD Struts Configuration 2.3//EN"
    "http://struts.apache.org/dtds/struts-2.3.dtd">
    
    <struts>
        <package name="swift" extends="struts-default" namespace="/">
            <action name="CustomerAction_*" class="customerAction" method="{1}">
                <result name="list" type="dispatcher">list.jsp</result>
                <result name="index" type="redirect">index.jsp</result>
            </action>
        </package>
    </struts>

可以弄个网页先试试好用不(单独测struts不用spring整合,需要把上边的class="customerAction"修改为Action类的全限定名)

index.jsp

<%@ 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>
欢迎您登录首页

<hr />
    <form action="${pageContext.request.contextPath }/CustomerAction_findById" method="post">
    <span>请输入客户编号:</span>
    <input type="text" name="cid" >
    <input type="submit" value="查询" >
    </form>
<hr />
    <form action="${pageContext.request.contextPath }/CustomerAction_add" method="post">
    <span>请录入客户姓名:</span>
    <input type="text" name="name" >
    <input type="submit" value="增加" >
    </form>
</body>
</html>

显示结果页list.jsp

<%@ 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>
    <table>
        <tr>
            <td>编号:</td><td><input type="text" value="${cus.cid }"></td>
        </tr>
        <tr>
            <td>姓名:</td><td><input type="text" value="${cus.name }"></td>
        </tr>
    </table>
</body>
</html>

需要开启struts的filter,(struts2就靠这个了)

web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" version="2.5">
  <display-name>ssh-maven</display-name>
  <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>
  <filter>
      <filter-name>struts2</filter-name>
      <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
  </filter>
  <filter-mapping>
      <filter-name>struts2</filter-name>
      <url-pattern>/*</url-pattern>
  </filter-mapping>
  
  <welcome-file-list>
    <welcome-file>index.jsp</welcome-file>
    <welcome-file>index.html</welcome-file>
    <welcome-file>index.htm</welcome-file>
    <welcome-file>default.html</welcome-file>
    <welcome-file>default.htm</welcome-file>
    <welcome-file>default.jsp</welcome-file>
  </welcome-file-list>
</web-app>

然后走到hibernate去,目录结构如下

maven ssh的xml环境搭建 及常见异常解决

实体类及其映射

package com.swift.entity;

public class Customer {

    private Integer cid;
    private String name;
    public Integer getCid() {
        return cid;
    }
    public void setCid(Integer cid) {
        this.cid = cid;
    }
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    @Override
    public String toString() {
        return "Customer [cid=" + cid + ", name=" + name + "]";
    }
    public Customer(Integer cid, String name) {
        this.cid = cid;
        this.name = name;
    }
    public Customer() {
    }
    
}

Customer.hbm.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-mapping PUBLIC 
    "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
    "http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd">
    
    <hibernate-mapping>
        <class name="com.swift.entity.Customer" table="tb_customer" >
            <id name="cid" column="cid">
                <generator class="native"></generator>
            </id>
            <property name="name" column="name"></property>
        </class>
    </hibernate-mapping>

CustomerDaoImpl.java 持久层实现类

package com.swift.dao.impl;

import org.springframework.orm.hibernate5.HibernateTemplate;

import com.swift.dao.CustomerDao;
import com.swift.entity.Customer;

public class CustomerDaoImpl implements CustomerDao{
    
    HibernateTemplate hibernateTemplate;
    
    public void setHibernateTemplate(HibernateTemplate hibernateTemplate) {
        this.hibernateTemplate = hibernateTemplate;
    }

    public Customer findById(Integer cid) {
        return hibernateTemplate.get(Customer.class, cid);
    }

    @Override
    public void add(Customer customer) {

        hibernateTemplate.save(customer);
    }

}

连接的库 db.properties

driverClass = oracle.jdbc.driver.OracleDriver
jdbcUrl=jdbc:oracle:thin:@192.168.189.101:1521:orcl
user=scott
password=tiger
#driverClass = com.mysql.jdbc.Driver
#jdbcUrl=jdbc:mysql://localhost:3306/maven
#user=root
#password=root

以及最后的spring核心配置文件进行整合

<?xml version="1.0" encoding="UTF-8"?>

    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:aop="http://www.springframework.org/schema/aop"

    </bean>
    
</beans>

常见异常解决

 

java.lang.ClassCastException: org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter cannot be cast to javax.servlet.Filter

这个异常要把servlet-api 改为provided
两个包都有相关内容会引起冲突,要把一个设置为从属(provided 级别低一级)

 

Line: 245 - com/opensymphony/xwork2/spring/SpringObjectFactory.java:245:-1

1.Struts与Spring不兼容,struts.xml中的action的class属性应注入Spring的bean
2.如果有struts2-spring-plugin-2.3.24.1.jar表明该插件引入工程后，会自动设置Struts的ObjectFactory为StrutsSpringObjectFactory，
从而让Spring的IOC容器来托管Struts的Action。但是工程web.xml中没有配置加载spring ApplicationContext相关的listener,所以导致了启动的问题。

 

java.sql.SQLException: ORA-00001: 违反唯一约束条件 (SCOTT.SYS_C0011456)

这个问题的原因是:customer.setCid(cid); 主键有自增或者sequence,与你提供的id冲突,执行添加操作hibernateTemplate.save(customer);时不设置customer
的id即可
