使用eclipse搭建SSM框架整合Maven（超详细！）

今天药忘吃喽~ 2022-05-16 14:08 527阅读 0赞

工作以来，一直在写前端，很久没碰后端了，今天突然发现，后端的东西得慢慢捡起来了，毕竟以后还是得靠后端吃饭的。要写后端，首先得有环境吧，那就从搭框架开始吧，今天先搭一个SSM框架，方便以后需要时直接用。下次有时间再写一个搭建SSH的。文章大部分内容参考传智播客教学视频，本文只列出搭建流程，一些固定代码还是能copy就copy吧^_^

1.使用eclipse新建一个Maven工程

70 1

2.填写项目的Maven坐标

3.添加项目依赖，完整pom.xml如下：

  1. <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  2.     xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

4.编写web.xml配置文件。

  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">

  39.     <!-- 
  40.         将POST请求转化为DELETE或者是PUT
  41.         要用_method指定真正的请求方法
  42.      -->
  43.     <filter>
  44.         <filter-name>HiddenHttpMethodFilter</filter-name>
  45.         <filter-class>org.springframework.web.filter.HiddenHttpMethodFilter</filter-class>

  60.          <load-on-startup>1</load-on-startup>
  61.     </servlet>
  63.     <servlet-mapping>
  64.         <servlet-name>itcast-usermanage</servlet-name>
  65.         <!-- 
  66.             可行：/、*.xxx、/xxx/*
  67.             不行：/*

  69.         <url-pattern>/rest/*</url-pattern>
  70.     </servlet-mapping>

  73.         <welcome-file>index.jsp</welcome-file>
  74.     </welcome-file-list>
  76. </web-app>

5.添加db.properties连接数据库的配置文件。本文连接的是mysql数据库。

  53. </beans>

7.编写spring事物配置文件：applicationContext-transaction.xml

  1. <beans xmlns="http://www.springframework.org/schema/beans"
  2.     xmlns:context="http://www.springframework.org/schema/context" xmlns:p="http://www.springframework.org/schema/p"
  3.     xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"

  32.         <aop:advisor advice-ref="txAdvice" pointcut-ref="myPointcut" />
  33.     </aop:config>
  35. </beans>

8.编写springMVC配置文件：itcast-usermanage-servlet.xml

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

  16.     <!-- 视图解析器 -->
  17.     <!-- 
  18.         Example: prefix="/WEB-INF/jsp/", suffix=".jsp", viewname="test" -> "/WEB-INF/jsp/test.jsp"

  22.         <property name="suffix" value=".jsp"/>
  23.     </bean>
  25. </beans>

9.编写mybatis和spring的整合文件:applicationContext-mybatis.xml

  1. <beans xmlns="http://www.springframework.org/schema/beans"
  2.     xmlns:context="http://www.springframework.org/schema/context" xmlns:p="http://www.springframework.org/schema/p"
  3.     xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"
  4.     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  5.     xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd
  6.     http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd
  7.     http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.0.xsd
  8.     http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-4.0.xsd">
  10.     <bean class="org.mybatis.spring.SqlSessionFactoryBean">
  11.         <!-- 数据源 -->
  12.         <property name="dataSource" ref="dataSource"/>
  13.         <!-- 配置Mybatis的全局配置文件 -->
  14.         <property name="configLocation" value="classpath:mybatis/mybatis-config.xml"/>
  15.         <!-- 配置mapper.xml文件 -->
  16.         <!-- <property name="mapperLocations" value="classpath:mybatis/mappers/*.xml"/> -->
  17.         <!-- 别名包 -->
  18.         <property name="typeAliasesPackage" value="cn.itcast.usermanage.pojo"/>
  19.     </bean>
  21.     <!-- mapper接口的扫描器 -->
  22.     <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
  23.         <property name="basePackage" value="cn.itcast.usermanage.mapper"/>
  24.     </bean>
  26. </beans>

注：以上四个文件可以写成一个配置文件，但是为了方便后期维护，分开写较好。

10.编写mybatis全局配置文件：mybatis-config.xml

  1. <?xml version="1.0" encoding="UTF-8" ?>

至此，SSM框架就搭建完成啦，剩下的就是往里面填东西了。其实框架这东西，就是搭建起来配置文件多比较麻烦，搭建完成后，用起来还是比较舒服的！要是嫌SSM框架太繁琐，可以用springboot微服务框架，少了很多复杂的配置文件，用起来也很方便！博客有搭建流程，有兴趣可以看看！
