尚籌網(wǎng)-1.后臺(tái)環(huán)境搭建

1. 后臺(tái)單一架構(gòu)介紹

1.1 概念

  • 整個(gè)項(xiàng)目都封裝到一個(gè)war包在一個(gè)Tomcat上運(yùn)行，這就是單一架構(gòu)模式赫冬。也叫“單機(jī)版”妇萄、“all in one”。
  • 優(yōu)點(diǎn)：結(jié)構(gòu)簡(jiǎn)單例证，不涉及模塊之間調(diào)用路呜。易于開(kāi)發(fā)和部署。
  • 缺點(diǎn)：不能容納規(guī)模龐大织咧、訪問(wèn)量高的項(xiàng)目拣宰。

1.2 工程之間的關(guān)系

1.3 創(chuàng)建Maven工程即Maven Module

1.4 工程創(chuàng)建清單

父工程坐標(biāo)

  • groupid：com.rgh.crowd.funding
  • artifactid：atcrowdfunding-admin-0-parent
  • packaging：pom

WebUI工程

  • Module Name：atcrowdfunding-admin-1-webui
  • 注意：打包方式選擇war

組件工程

  • Module Name：atcrowdfunding-admin-2-component

通用工程

  • Module Name：atcrowdfunding-admin-3-common

2.4 執(zhí)行逆向生成操作的Maven命令

2.5 逆向工程生成的資源各歸各位

逆向工程目錄

項(xiàng)目工程目錄

WebUI工程將來(lái)在Tomcat上運(yùn)行時(shí)绿渣，現(xiàn)在resources目錄下的資源會(huì)直接放在WEB-INF/classes目錄（也就是類(lèi)路徑）下朝群，所以放在resources目錄下運(yùn)行的時(shí)候更容易找到。

3.1 創(chuàng)建包

  • com.rgh.crowd.funding.service
  • com.rgh.crowd.funding.service.api
  • com.rgh.crowd.funding.service.impl

4. SSM整合總體思路

5. Spring和MyBatis整合

5.1 創(chuàng)建Spring配置文件

  • spring-persist-mybatis.xml
  • spring-persist-tx.xml
  • spring-web-mvc.xml

5.2 創(chuàng)建jdbc.properties

jdbc.user=root
jdbc.password=360
jdbc.url=jdbc:mysql://localhost:3306/atcrowdfunding190105
jdbc.driver=com.mysql.jdbc.Driver

5.3 創(chuàng)建log4j.properties

log4j.rootLogger=DEBUG,myConsole
log4j.appender.myConsole=org.apache.log4j.ConsoleAppender
log4j.appender.myConsole.Target=System.out
log4j.appender.myConsole.layout=org.apache.log4j.PatternLayout
log4j.appender.myConsole.layout.ConversionPattern=%p [%C{1}:%L] %m%n

5.4 配置數(shù)據(jù)源

所在配置文件spring-persist-mybatis.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:context="http://www.springframework.org/schema/context"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.3.xsd">
    <!-- 加載外部屬性文件 -->
    <context:property-placeholder location="classpath:jdbc.properties"/>

    <!-- 配置數(shù)據(jù)源 -->
    <bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource">
        <property name="username" value="${jdbc.user}"/>
        <property name="password" value="${jdbc.password}"/>
        <property name="url" value="${jdbc.url}"/>
        <property name="driverClassName" value="${jdbc.driver}"/>
    </bean>

5.5 測(cè)試類(lèi)

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = {"classpath:spring-persist-mybatis.xml","classpath:spring-persist-tx.xml"})
public class CrowdFundingTest {
    @Autowired
    private DataSource dataSource;
    @Test
    public void testConnection() throws SQLException {
        Connection connection = dataSource.getConnection();
        System.out.println(connection);
    }
}

所需依賴(lài)webui-pom.xml

<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-test</artifactId>
    <scope>test</scope>
</dependency>
<dependency>
    <groupId>junit</groupId>
    <artifactId>junit</artifactId>
    <scope>test</scope>
</dependency>

5.6 創(chuàng)建MyBatis全局配置文件

mybatis-config.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN" "http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>
</configuration>

5.7 配置SqlSessionFactoryBean

所在的配置文件：spring-persist-mybatis.xml

<!-- 配置SqlSessionFactoryBean -->
<bean id="sqlSessionFactoryBean" class="org.mybatis.spring.SqlSessionFactoryBean">

    <!-- MyBatis配置文件所在位置 -->
    <property name="configLocation" value="classpath:mybatis/mybatis-config.xml"/>

    <!-- 配置Mapper配置文件位置 -->
    <property name="mapperLocations" value="classpath:mybatis/mapper/*Mapper.xml"/>

    <!-- 裝配數(shù)據(jù)源 -->
    <property name="dataSource" ref="dataSource"/>

</bean>
<!-- 配置MyBatis掃描器 -->
<bean id="mapperScannerConfigurer" class="org.mybatis.spring.mapper.MapperScannerConfigurer">
    <!-- 指定Mapper接口所在包 -->
    <property name="basePackage" value="com.rgh.crowd.funding.mapper"/>
</bean>

5.8 測(cè)試整合效果

CrowdFundingTest.java

@Autowired
private AdminService adminService;

@Test
public void testMybatis() {
    List<Admin> adminList = adminService.getAll();
    for (Admin admin : adminList) {
        System.out.println(admin);
    }
}

spring-persist-mybatis.xml中配置掃描服務(wù)層

<!-- 掃描AdminService -->
<context:component-scan base-package="com.rgh.crowd.funding.service.*"/>

6. 配置聲明式事務(wù)

所在配置文件：spring-persist-tx.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:aop="http://www.springframework.org/schema/aop"

        http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.3.xsd">

    <!-- 配置事務(wù)管理器 -->
    <bean id="dataSourceTransactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <property name="dataSource" ref="dataSource"/>
    </bean>

    <!-- 配置事務(wù)通知 -->
    <tx:advice id="txAdvice" transaction-manager="dataSourceTransactionManager">
        <!-- 配置事務(wù)屬性 -->
        <tx:attributes>
            <!-- 將查詢(xún)方法設(shè)置為只讀 -->
            <tx:method name="get*" read-only="true"/>
            <tx:method name="query*" read-only="true"/>
            <tx:method name="find*" read-only="true"/>
            <tx:method name="count*" read-only="true"/>

            <!-- 給增刪改方法設(shè)置屬性 -->
            <!-- propagation：配置傳播行為中符，REQUIRES_NEW表示必須工作在自己新開(kāi)的事務(wù)中姜胖，不受其他事務(wù)回滾影響 -->
            <!-- rollback-for：配置回滾的異常，默認(rèn)是根據(jù)運(yùn)行時(shí)異车砩ⅲ回滾右莱，為了拋出編譯時(shí)異常也回滾，設(shè)置為java.lang.Exception -->
            <tx:method name="save*" propagation="REQUIRES_NEW" rollback-for="java.lang.Exception"/>
            <tx:method name="remove*" propagation="REQUIRES_NEW" rollback-for="java.lang.Exception"/>
            <tx:method name="update*" propagation="REQUIRES_NEW" rollback-for="java.lang.Exception"/>

        </tx:attributes>
    </tx:advice>

    <!-- 配置事務(wù)切面 -->
    <aop:config>

        <!-- 切入點(diǎn)表達(dá)式 -->
        <aop:pointcut expression="execution(* *..*Service.*(..))" id="txPointCut"/>

        <!-- 將事務(wù)通知和切入點(diǎn)表達(dá)式關(guān)聯(lián)起來(lái) -->
        <aop:advisor advice-ref="txAdvice" pointcut-ref="txPointCut"/>
    </aop:config>

    <!-- @Transactional -->
    <!-- <tx:annotation-driven transaction-manager="dataSourceTransactionManager"/> -->

</beans>

7. 加入Spring MVC

7.1 配置spring-web-mvc.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:mvc="http://www.springframework.org/schema/mvc"
       xmlns:context="http://www.springframework.org/schema/context"
       xsi:schemaLocation="http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.3.xsd
        http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.3.xsd">

    <!-- 配置自動(dòng)掃描的包 -->
    <context:component-scan base-package="com.rgh.crowd.funding.handler"/>

    <!-- 配置SpringMVC標(biāo)配：注解驅(qū)動(dòng) -->
    <mvc:annotation-driven/>

    <!-- 配置視圖解析器 -->
    <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/"/>
        <property name="suffix" value=".jsp"/>
    </bean>

</beans>

7.2 配置web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xmlns="http://xmlns.jcp.org/xml/ns/javaee"
         xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"
         version="3.1">

    <!-- needed for ContextLoaderListener -->
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:spring-persist-*.xml</param-value>
    </context-param>

    <!-- Bootstraps the root web application context before servlet initialization -->
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>

    <!-- The front controller of this Spring Web application, responsible for handling all application requests -->
    <servlet>
        <servlet-name>springDispatcherServlet</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>classpath:spring-web-mvc.xml</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>

    <!-- Map all requests to the DispatcherServlet for handling -->
    <servlet-mapping>
        <servlet-name>springDispatcherServlet</servlet-name>
        <url-pattern>*.html</url-pattern>
        <url-pattern>*.json</url-pattern>
    </servlet-mapping>

    <filter>
        <filter-name>CharacterEncodingFilter</filter-name>
        <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
        <init-param>
            <param-name>encoding</param-name>
            <param-value>UTF-8</param-value>

            <param-value>true</param-value>
        </init-param>
        <init-param>
            <param-name>forceResponseEncoding</param-name>
            <param-value>true</param-value>
        </init-param>
    </filter>
    <filter-mapping>
        <filter-name>CharacterEncodingFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

</web-app>

7.3 偽靜態(tài)【了解】

DispatcherServlet映射*.html擴(kuò)展名档插，那么所有以html結(jié)尾的請(qǐng)求都由SpringMVC處理慢蜓。反之，請(qǐng)求地址沒(méi)有以html結(jié)尾郭膛，不會(huì)由SpringMVC處理晨抡。

這樣就可以把一個(gè)本來(lái)是動(dòng)態(tài)處理的請(qǐng)求看起來(lái)像是請(qǐng)求了一個(gè)HTML頁(yè)面。

好處1：增加黑客入侵的難度则剃。

好處2：有利于SEO優(yōu)化耘柱。

注意：如果實(shí)質(zhì)上返回的響應(yīng)數(shù)據(jù)是JSON格式，那么Tomcat將認(rèn)為這個(gè)響應(yīng)數(shù)據(jù)和請(qǐng)求擴(kuò)展名“html”不匹配棍现，然后給出415錯(cuò)誤调煎。針對(duì)這種情況，需要另外再映射*.json擴(kuò)展名轴咱。

7.4 創(chuàng)建Controller類(lèi)測(cè)試

@Controller
public class AdminHandler {

    @Autowired
    private AdminService adminService;

    @RequestMapping("/admin/get/all")
    public String getAll(Model model){
        List<Admin> list = adminService.getAll();
        model.addAttribute("list",list);
        return "admin-target";
    }

}

目標(biāo)頁(yè)面jsp

7.5 在 atcrowdfunding-admin-1-webui的pom.xml加入依賴(lài)

<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>servlet-api</artifactId>
    <scope>provided</scope>
</dependency>
<dependency>
    <groupId>javax.servlet.jsp</groupId>
    <artifactId>jsp-api</artifactId>
    <scope>provided</scope>
</dependency>
<dependency>
    <groupId>jstl</groupId>
    <artifactId>jstl</artifactId>
</dependency>

admin-target.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8"
