（摘錄筆記）JAVA學習筆記SSH整合搭建項目

標籤：

1：當然是導jar包啦；

struts2：

spring：

hibernate：

至於這些jar包是什麼作用，我想就不必我解釋了，大家都懂得，ssh2基本的jar包；

還有一些其他jar包：struts2-spring-plugin-2.1.8.1.jar(struts2-spring整合使用的jar包) ， c3p0-0.9.2-pre1.jar（使用連結池連結資料庫）

2：添加struts.xml檔案

<?xml version="1.0" encoding="UTF-8" ?><!DOCTYPE struts PUBLIC        "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"        "http://struts.apache.org/dtds/struts-2.0.dtd"><struts>    <!-- Overwrite Convention -->    <package name="users" namespace="/lishun" extends="struts-default">    <!-- 這裡的action是叫spring管理了，所以這裡的class屬性值是寫的是該被注入Action的id名稱，後面的action類會有提到 -->        <action name="users" class="usersAction" method="execute">            <result name="success">/index.jsp</result>        </action>    </package></struts>

配置web.xml

<?xml version="1.0" encoding="UTF-8"?><web-app version="3.0" xmlns="http://java.sun.com/xml/ns/javaee"    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee     http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd">    <display-name></display-name>    <welcome-file-list>        <welcome-file>index.jsp</welcome-file>    </welcome-file-list>    <!-- 定義struts的核心監聽器 -->    <filter>        <filter-name>action2</filter-name>        <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>    </filter>    <filter-mapping>        <filter-name>action2</filter-name>        <url-pattern>/*</url-pattern>    </filter-mapping>        　　　　        <!-- 把struts與spring整合;;一定不要忘記導struts2-spring-plugin-2.1.8.1.jar 包 -->    <listener>        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>    </listener>    <context-param>        <param-name>contextConfigLocation</param-name>        <param-value>classpath:application.xml</param-value>    </context-param></web-app>

配置hibernate.cfg.xml

<!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN" 
"http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd"><hibernate-configuration>    <session-factory>        <!-- 執行資料庫操作時顯示sql語句 -->        <property name="show_sql">true</property>        <property name="dialect">            org.hibernate.dialect.MySQLDialect        </property>        <!-- 自動建表：若表不存在就建立表，若存在就不建立，若實體類發生改變就重新建立表 -->        <property name="hbm2ddl.auto">update</property>        <!-- 匯入對應檔 -->        <mapping resource="com/lishun/domian/Users.hbm.xml" />    </session-factory></hibernate-configuration>

配置application.xml

DataBaseConnection.properties屬性檔案

 

3：測試

這是我的目錄結構，是一層調用著一層

控制器Action：

@Controller("usersAction")//控制器註解,並定義改bean的id是usersAction，@Scope("prototype")//聲明bean的範圍為prototype：每次從容器擷取bean都是新的對象。public class UsersAction extends ActionSupport {        @Resource    private IUserService servise;    public String execute(){        servise.sava();        return "success";    }}

業務層seivice：

@Service//service層註解public class UserServiceBean implements IUserService {    //給屬性注入值    @Resource    public IUserDao userDao;    @Override    @Transactional //這個方法會自動開啟事務和提交事務，當有異常時就復原事務    public void sava() {        userDao.sava();    }}

資料操作層dao：

public class UserDaoBean implements IUserDao {    //從設定檔注入sessionfactory值    @Resource    private SessionFactory seesionFactory;    @Override    public void sava() {        Session session = seesionFactory.getCurrentSession();        System.out.println(session);        Users u=new Users();        u.setUname("王尼瑪");        session.save(u);    }}

最有一個javabean實體，這個實體很簡單就只有id和name兩個欄位，測試用的沒弄很多欄位上去

public class Users {    private Integer uid;    private String uname;    public Integer getUid() {        return uid;    }    public void setUid(Integer uid) {        this.uid = uid;    }    public String getUname() {        return uname;    }    public void setUname(String uname) {        this.uname = uname;    }    @Override    public String toString() {        return "Users [uid=" + uid + ", uname=" + uname + "]";    }}

對應的對應檔

<?xml version="1.0"?><!DOCTYPE hibernate-mapping PUBLIC"-//Hibernate/Hibernate Mapping DTD 3.0//EN""http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd"><hibernate-mapping package="com.lishun.domian" > <!-- 定義類名和對應的表名 -->  <class name="Users" table="tb_users">      <id name="uid" type="integer">        <!-- 主鍵是自增的 -->         <generator class="native"></generator>    </id>    <property name="uname"  type="string">    </property>  </class></hibernate-mapping>
