SSM環境搭建

環境準備

1.1 數據庫與表結構

創建用戶與授權

數據庫我們使用Oracle Oracle 爲每個項目創建單獨user，oracle數據表存放在表空間下，每個用戶有獨立表空間

創建用戶及密碼：

語法[創建用戶]： create user 用戶名 identified by 口令[即密碼]； 
例子： create user test identified by test;

授權

語法： grant connect, resource to 用戶名; 
例子： grant connect, resource to

連接oracle數據庫

PL/SQL Developer是一個集成開發環境，專門面向Oracle數據庫存儲程序單元的開發PL/SQL Developer側重於易用性、代碼品質和生產力，充分發揮Oracle應用程序開發過程中的主要優勢。

創建用戶及授權
a) 創建用戶

b) 授權

對象權限是指針對於某一張表的操作權限,系統權限是指對錶的CRUD操作權限, 角色權限是系統權限的集合,我們設置時，一般是設置角色權限，設置resource與connect

創建表

CREATE TABLE product(

id varchar2(32) default SYS_GUID() PRIMARY KEY,

productNum VARCHAR2(50) NOT NULL,

productName VARCHAR2(50),

cityName VARCHAR2(50),

DepartureTime timestamp,

productPrice Number,

productDesc VARCHAR2(500),

productStatus INT,

CONSTRAINT product UNIQUE (id, productNum)

)

insert into PRODUCT (id, productnum, productname, cityname, departuretime, productprice, productdesc, productstatus)

values ('676C5BD1D35E429A8C2E114939C5685A', 'itcast-002', '北京三日遊', '北京', to_timestamp('10-10-2018 10:10:00.000000', 'dd-mm-yyyy hh24:mi:ss.ff'), 1200, '不錯的旅行', 1);

insert into PRODUCT (id, productnum, productname, cityname, departuretime, productprice, productdesc, productstatus)

values ('12B7ABF2A4C544568B0A7C69F36BF8B7', 'itcast-003', '上海五日遊', '上海', to_timestamp('25-04-2018 14:30:00.000000', 'dd-mm-yyyy hh24:mi:ss.ff'), 1800, '魔都我來了', 0);

insert into PRODUCT (id, productnum, productname, cityname, departuretime, productprice, productdesc, productstatus)

values ('9F71F01CB448476DAFB309AA6DF9497F', 'itcast-001', '北京三日遊', '北京', to_timestamp('10-10-2018 10:10:00.000000', 'dd-mm-yyyy hh24:mi:ss.ff'), 1200, '不錯的旅行', 1);

1.3編寫實體類

public class Product {

private String id; // 主鍵

private String productNum; // 編號 唯一

private String productName; // 名稱

private String cityName; // 出發城市

private Date departureTime; // 出發時間

private String departureTimeStr;

private double productPrice; // 產品價格

private String productDesc; // 產品描述

private Integer productStatus; // 狀態 0 關閉 1 開啓 private String productStatusStr;

}

編寫接口

業務

public interface IProductService {

List<Product> findAll() throws Exception;

}

持久層

public interface IProductDao {

@Select("select * from product")

List<Product> findAll() throws Exception;

}

SSM整合(web)與產品查詢

Spring環境搭建

2.1.1.編寫Spring配置文件applicationContext.xml

 <!-- 1.開啓註解掃描，管理service和dao -->
    <context:component-scan base-package="com.itheima.ssm.service">
    </context:component-scan>
    <context:component-scan base-package="com.itheima.ssm.dao">
    </context:component-scan>
    
<!--2.Spring與MyBatis整合-->
    <context:property-placeholder location="classpath:db.properties"/>
    <!-- 配置連接池 -->
    <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
        <property name="driverClass" value="${jdbc.driver}"/>
        <property name="jdbcUrl" value="${jdbc.url}"/>
        <property name="user" value="${jdbc.username}"/>
        <property name="password" value="${jdbc.password}"/>
    </bean>
    <!-- 把交給IOC管理 SqlSessionFactory -->
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="dataSource" ref="dataSource"/>
    </bean>
    <!-- 掃描所有Mapper(dao)接口 -->
    <bean id="mapperScanner" class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="basePackage" value="com.itheima.ssm.dao"/>
    </bean>

    <!--3. 配置Spring的聲明式事務管理 -->
    <!-- 配置事務管理器 -->
    <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <property name="dataSource" ref="dataSource"/>
    </bean>

    <tx:annotation-driven transaction-manager="transactionManager"/>
</beans>

Spring與MyBatis整合
把 mybatis 配置文件（mybatis.xml）中內容配置到 spring 配置文件中同時，把 mybatis 配置文件的內容清掉。

由於我們使用的是代理 Dao ， 的模式，Dao 具體實現類由 MyBatis 使用代理方式創建，所以此時 mybatis 配置文件不能刪。 當我們整合 spring 和 mybatis 時，mybatis 創建的 Mapper.xml 文件名必須和 Dao 接口 文件 名一致

2.1.2.使用註解配置業務層

@Service

public class ProductServiceImpl implements IProductService{

@Override

public List<Product> findAll() throws Exception { return null;

}

}

web.xml 配置

<!--Spring與Spring MVC整合-->
	<!-- 配置加載類路徑的配置文件 -->
	<context-param>
		<param-name>contextConfigLocation</param-name>
		<param-value>classpath*:applicationContext.xml,classpath*:spring-security.xml</param-value>
	</context-param>

<!-- 配置監聽器 -->
	<listener>
		<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
	</listener>
	<!-- 配置監聽器，監聽request域對象的創建和銷燬的 -->
	<listener>
		<listener-class>org.springframework.web.context.request.RequestContextListener</listener-class>
	</listener>

	

<!-- 配置 spring mvc 的核心控制器 -->
	<!-- 前端控制器（加載classpath:springmvc.xml 服務器啓動創建servlet） -->
	<servlet>
		<servlet-name>dispatcherServlet</servlet-name>
		<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
		<!-- 配置初始化參數，創建完DispatcherServlet對象，加載springmvc.xml配置文件 -->
		<init-param>
			<param-name>contextConfigLocation</param-name>
			<param-value>classpath:springmvc.xml</param-value>
		</init-param>
		<!-- 服務器啓動的時候，讓DispatcherServlet對象創建 -->
		<!-- 配置 servlet 的對象的創建時間點：應用加載時創建。取值只能是非 0 正整數，表示啓動順 序 -->
		<load-on-startup>1</load-on-startup>
	</servlet>
	<servlet-mapping>
		<servlet-name>dispatcherServlet</servlet-name>
		<url-pattern>*.do</url-pattern>
	</servlet-mapping>

	<!-- 解決中文亂碼過濾器 配置 springMVC 編碼過濾器-->
	<filter>
		<filter-name>characterEncodingFilter</filter-name>
		<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
		<!-- 設置過濾器中的屬性值 -->
		<init-param>
			<param-name>encoding</param-name>
			<param-value>UTF-8</param-value>
		</init-param>
	</filter>
	<!-- 過濾所有請求 -->
	<filter-mapping>

		<url-pattern>/*</url-pattern>
	</filter-mapping>

	<!-- 委派過濾器 權限驗證過濾器-->
	<filter>

		<filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
	</filter>
	<filter-mapping>
		<filter-name>springSecurityFilterChain</filter-name>
		<url-pattern>/*</url-pattern>
	</filter-mapping>

	<welcome-file-list>

		<welcome-file>index.htm</welcome-file>
		<welcome-file>index.jsp</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>

Spring MVC 環境搭建

2.2.2.Spring MVC配置文件springmvc.xml

    <!-- 掃描controller的註解，別的不掃描 -->
    <context:component-scan base-package="com.itheima.ssm.controller">
    </context:component-scan>

    <!-- 配置視圖解析器 -->
    <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <!-- JSP文件所在的目錄 -->
        <property name="prefix" value="/pages/" />
        <!-- 文件的後綴名 -->
        <property name="suffix" value=".jsp" />
    </bean>

    <!-- 設置靜態資源不過濾 -->
    <mvc:resources location="/css/" mapping="/css/**" />
    <mvc:resources location="/img/" mapping="/img/**" />
    <mvc:resources location="/js/" mapping="/js/**" />
    <mvc:resources location="/plugins/" mapping="/plugins/**" />

    <!-- 開啓對SpringMVC註解的支持 -->
    <mvc:annotation-driven />

    <!--
        支持AOP的註解支持，AOP底層使用代理技術
        JDK動態代理，要求必須有接口
        cglib代理，生成子類對象，proxy-target-class="true" 默認使用cglib的方式
    -->
    <aop:aspectj-autoproxy proxy-target-class="true"/>

</beans>

2.2.3.編寫ProductController

@Controller

@RequestMapping("/product")

public class ProductController {

@Autowired

private IProductService productService;

@RequestMapping("/findAll.do")

public ModelAndView findAll() {

return null;

}

}

測試運行
