IDEA從0搭建SSM專案【圖文】（一）——本地執行Hello World
阿新 • • 發佈：2019-01-27
記得初學SSM時，跟著網上的教程走，一步一坑，為了讓更多的初學者體驗一次搭建好SSM的快感，本人利用工作之餘撰寫此篇教程。
一，環境準備
1.IDEA工具
2.maven
① 配置到環境變數
② 將maven新增到IDEA
圖中Local repository本地倉庫使用預設m2就好【我這裡是在配置檔案裡修改過了】
3.tomcat
這個應該都會，配置到IDEA
4.mysql
記得登入名和密碼即可，將寫入專案配置檔案db.properties
本文用的5.7（注意5.7以後的mysql驅動不一樣，是com.mysql.cj.jdbc.Driver）
5.jdk
本文用的1.8
二，搭建空專案
1.新建空專案
2.選擇maven，點選next
3.隨便填寫GroupId和ArtifactId，點選next
4.填寫專案名稱，擊next
5.finish，專案結構如圖
6.新增webapp資料夾【因為是J2EE專案】
① 點選project structure
② 新增web模組
③ 如圖，點選鉛筆，替換路徑【上面，下面都替換】中的\web為\src\main\webapp
④ 修改完如圖
⑤ 點選ok，即自動生成如下目錄
三，配置pom.xml，web.xml，新建spring mvc配置檔案
1. pom.xml新增spring相關依賴
貼上即可，有註釋
<dependencies>主要就是spring相關包，servlet包，mysql連線包
<build>本地執行暫時用不著
<?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>Test</groupId> <artifactId>Test</artifactId> <version>1.0-SNAPSHOT</version> <properties> <spring.version>4.3.18.RELEASE</spring.version> </properties> <dependencies> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>${spring.version}</version> </dependency> <!--servlet&jsp--> <!-- https://mvnrepository.com/artifact/javax.servlet/javax.servlet-api --> <dependency> <groupId>javax.servlet</groupId> <artifactId>javax.servlet-api</artifactId> <version>3.1.0</version> <scope>provided</scope> </dependency> <!-- https://mvnrepository.com/artifact/javax.servlet.jsp/javax.servlet.jsp-api --> <dependency> <groupId>javax.servlet.jsp</groupId> <artifactId>javax.servlet.jsp-api</artifactId> <version>2.2.1</version> <scope>provided</scope> </dependency> <!-- https://mvnrepository.com/artifact/org.apache.tomcat/tomcat-servlet-api --> <dependency> <groupId>org.apache.tomcat</groupId> <artifactId>tomcat-servlet-api</artifactId> <version>8.5.33</version> </dependency> <!--Spring與Mybatis整合--> <!-- https://mvnrepository.com/artifact/org.mybatis/mybatis --> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis</artifactId> <version>3.4.1</version> </dependency> <!-- https://mvnrepository.com/artifact/org.mybatis/mybatis-spring --> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis-spring</artifactId> <version>1.3.2</version> </dependency> <!-- https://mvnrepository.com/artifact/mysql/mysql-connector-java --> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>5.1.43</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-tx</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-jdbc</artifactId> <version>${spring.version}</version> </dependency> <!--dataSource連線池--> <!-- https://mvnrepository.com/artifact/org.apache.commons/commons-dbcp2 --> <dependency> <groupId>org.apache.commons</groupId> <artifactId>commons-dbcp2</artifactId> <version>2.5.0</version> </dependency> </dependencies> <build> <plugins> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-compiler-plugin</artifactId> <!-- maven compiler plugin版本必須正確否則下面設定的JDK版本不起作用 --> <version>3.5.1</version> <configuration> <source>1.8</source> <target>1.8</target> </configuration> </plugin> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-war-plugin</artifactId> <version>3.2.0</version> <configuration> <webXml>src\main\webapp\WEB-INF\web.xml</webXml> </configuration> </plugin> </plugins> </build> </project>
2.web.xml配置spring mvc
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="
http://xmlns.jcp.org/xml/ns/javaee
http://xmlns.jcp.org/xml/ns/javaee/web-app_4_0.xsd"
version="4.0">
<!--字元編碼過濾器-->
<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>
</init-param>
<init-param>
<param-name>forceRequestEncoding</param-name>
<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>
<!--啟動Spring容器-->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:applicationContext.xml</param-value>
</context-param>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<!--啟動SpringMVC容器-->
<servlet>
<servlet-name>springmvc</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:springmvc.xml</param-value>
</init-param>
</servlet>
<servlet-mapping>
<servlet-name>springmvc</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
</web-app>
3.spring mvc配置檔案
<?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"
xmlns:mvc="http://www.springframework.org/schema/mvc"
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.xsd
http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc.xsd
">
<!--掃描controller-->
<context:component-scan base-package="com.hand.controller"/>
<!--配置檢視解析器-->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/views/"/>
<property name="suffix" value=".html"/>
</bean>
<!--靜態資源交給default-servlet處理-->
<mvc:default-servlet-handler/>
<mvc:annotation-driven/>
</beans>
4.新建controller和WEB-INF/views/hello.html【要在WEB-INF/views下，因為前面mvc配置檔案裡配的該路徑，你也可以修改】
5.poject structure新建web應用，並新增到tomcat
點OK
部署到本地tomcat伺服器
OK，執行，訪問瀏覽器
這篇其實只是準備工作，主要是搭建+spring+spring mvc，下一篇在此基礎上完善，進行真正的SSM增刪改查~
