• SSH_框架整合1

    1　WEB环境下配置Spring

    　   因为是在WEB环境中应用Spring,所以要先配置web.xml:

        (1)WebContent-WEB-INF-lib包中，加入Spring包下的required的所有jar包；

    　 (2)WebContent-WEB-INF下新建web.xml,配置web.xml

     1 <?xml version="1.0" encoding="UTF-8"?>
 2 <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" id="WebApp_ID" version="2.5">
 3     
 4     <!-- 配置spring配置文件.xml的名称和位置路径 -->
 5     <context-param>
 6         <param-name>contextConfigLocation</param-name>
 7         <param-value>classpath:applicationContext*.xml</param-value>
 8     </context-param>
 9     
10     <!-- Bootstraps the root web application context before servlet initialization -->
11     <listener>
12         <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
13     </listener>
14     
15 
16 </web-app>

        (3)src下新建Source-folder包：conf，新建applicationContext.xml（暂时不需要写）

     

    2 加入Hibernate

    　　(1)建立持久化类，生成对应的 .hbm.xml 文件, 生成对应的数据表；

    　　(2)Spring整合Hibernate

    　　(3) 步骤：

    　　　　①加入Hibernate的jar包，加入MySQL和c3p0驱动；

    　　　　②conf报下配置hibernate.cfg.xml文件

    　　 
     1 <?xml version="1.0" encoding="UTF-8"?>
 2 <!DOCTYPE hibernate-configuration PUBLIC
 3         "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
 4         "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
 5 <hibernate-configuration>
 6     <session-factory>
 7         
 8         <property name="hibernate.dialect">org.hibernate.dialect.MySQL5InnoDBDialect</property>
 9         <property name="hibernate.show_sql">true</property>
10         <property name="hibernate.format_sql">true</property>
11         <property name="hibernate.hbm2ddl.auto">update</property>
12     </session-factory>
13 </hibernate-configuration>
    View Code

    　　　　③src下新建实体类：com.atguigu.ssh.entities：Department.java和Employee.java　　

    Department.java：
    　　 
     1 package com.atguigu.ssh.entities;
 2 
 3 public class Department {
 4     
 5     private Integer id;
 6     private String departmentName="";
 7     public Integer getId() {
 8         return id;
 9     }
10     public void setId(Integer id) {
11         this.id = id;
12     }
13     public String getDepartmentName() {
14         return departmentName;
15     }
16     public void setDepartmentName(String departmentName) {
17         this.departmentName = departmentName;
18     }
19     
20     
21 }
    View Code
    Employee.java：
    　　 
     1 package com.atguigu.ssh.entities;
 2 
 3 import java.util.Date;
 4 
 5 public class Employee {
 6     private Integer id;
 7     
 8     private String lastName="";
 9     private String email;
10     
11     private Date birth;
12     private Date createTime;
13     
14     private Department department;
15 
16     public Integer getId() {
17         return id;
18     }
19 
20     public void setId(Integer id) {
21         this.id = id;
22     }
23 
24     public String getLastName() {
25         return lastName;
26     }
27 
28     public void setLastName(String lastName) {
29         this.lastName = lastName;
30     }
31 
32     public String getEmail() {
33         return email;
34     }
35 
36     public void setEmail(String email) {
37         this.email = email;
38     }
39 
40     public Date getBirth() {
41         return birth;
42     }
43 
44     public void setBirth(Date birth) {
45         this.birth = birth;
46     }
47 
48     public Date getCreateTime() {
49         return createTime;
50     }
51 
52     public void setCreateTime(Date createTime) {
53         this.createTime = createTime;
54     }
55 
56     public Department getDepartment() {
57         return department;
58     }
59 
60     public void setDepartment(Department department) {
61         this.department = department;
62     }
63     
64 }
    View Code

    　　 　　④生成对应的.hbm.xml持久化类映射文件：Department.hbm.xml，Employee.hbm.xml

     　　　　⑤conf包下新建db.properties文件：　

    　　 
    1 jdbc.user=root
2 jdbc.password=920614
3 jdbc.driverClass=com.mysql.jdbc.Driver
4 jdbc.jdbcUrl=jdbc:mysql:///spring_ssh
5 
6 jdbc.initPoolSize=5
7 jdbc.maxPoolSize=10
8 #...
    View Code

    　　　　⑥再次配置Spring配置文件：applicationContext.xml
