Maven+Eclipse（STS）搭建SSM项目笔记

2019-02-21  本文已影响0人  Bertram_Wang

准备开发环境；
jdk1.8， maven， tomcat 9.0， mysql
框架技术
spring + springmvc + mybatis + jsp

首先打开STS创建一个Maven项目；一直下一步创建时选择如图；


选择项目类型

创建完后效果如图：

错误信息：The superclass "javax.servlet.http.HttpServlet" was not found on the Java Build Path；-===>“avax.servlet.http超类”。在Java构建路径中没有找到HttpServlet；

刚创建的项目提示错误信息

处理方式：右击项目名ssm2--> 选择Build Path--> Add Libraries... -->选择Service Runtime --> next --> 选择Apache Tomcat(要有添加Tomcat) --> finish;

添加了Apache Tomcat后还是和正常的项目文档结构不一致，以及提示2个警告。

文档结构缺少以及警告版本冲突

缺少的文档处理方式。

右击项目名ssm2--> 选择Build Path --> Configure Build Path... -->选择Source --> 选中带有X的文件夹remove；

右击项目名ssm2--> 选择Build Path --> New Source Folder...; 分别创建src/main/java; src/test/java; src/test/resources;三个文件夹即可；

版本冲突警告处理方式。

右击项目名ssm2--> 选择Properties (前面两步也可以直接按快捷键 alt + enter)--> 选择Project Facets --> 修改java 版本从1.5改为1.8 --> finish;

执行ssm2; 效果图

项目创建展示

到此为止项目创建成功。接下来就是ssm框架的整合。
不多说直接上代码，pom.xml文件引入jar

在引入jar时不能被打断不然会引起jar包下载不完全的问题。
创建spring-mybatis.xml文件配置mybatis；主要配置的有以下信息：
datasource； SqlSessionFactory; MapperScannerConfigurer; transactionManager;

<beans xmlns="http://www.springframework.org/schema/beans"

http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-4.0.xsd">
<!-- 加载配置文件 -->
<!-- <context:property-placeholder location="classpath:jdbc.properties" /> -->
<!-- 数据库连接池 -->
<bean id="datasource" class="com.alibaba.druid.pool.DruidDataSource" destroy-method="close">
    <property name="url" value="jdbc:mysql://47.98.111.133:3306/personal-crm?useUnicode=true&amp;characterEncoding=utf8&amp;useSSL=false&amp;serverTimezone=GMT%2B8"/>
    <property name="username" value="root" />
    <property name="password" value="root" />

</bean>
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
    <property name="dataSource" ref="datasource"></property>
    <!-- 指定实体包 -->
    <property name="typeAliasesPackage" value="com.ssm.entity"></property>
    <!-- sql映射文件路径 mapper/任何包/任何以Mapper结尾的xml文件 -->
    <property name="mapperLocations" value="classpath:mapper/*Mapper.xml"></property>
</bean>
<!-- 自动扫描对象关系映射 -->
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
    <!--指定会话工厂，如果当前上下文中只定义了一个则该属性可省去 -->
    <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"></property>
    <!-- 指定要自动扫描接口的基础包，实现接口 -->
    <property name="basePackage" value="com.ssm.mapper"></property>
</bean>
<!-- 声明式事务管理 -->
<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
    <property name="dataSource" ref="datasource"></property>
</bean>
<!--支持注解驱动的事务管理，指定事务管理器 -->
<tx:annotation-driven transaction-manager="transactionManager"/>
<!-- 容器自动扫描IOC组件  -->
<context:component-scan base-package="com.ssm"></context:component-scan>
<!-- aspectj支持自动代理实现AOP功能 -->
<aop:aspectj-autoproxy proxy-target-class="true"></aop:aspectj-autoproxy>
</beans>

配置spring-mvc信息spring-mvc.xml

<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p"
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/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd
    http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">

<!-- 扫描controller -->
<context:component-scan base-package="com.ssm.controller" />

<!-- Spring 来扫描指定包下的类，并注册被@Component，@Controller，@Service，@Repository等注解标记的组件 -->
<mvc:annotation-driven />

<!-- 配置SpringMVC的视图解析器-->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
    <!-- 指定jsp文件路径 -->
    <property name="prefix" value="/WEB-INF/views/" />
    <property name="suffix" value=".jsp" />
</bean>
</beans>

最后在web.xml文件中使用即可

<?xml version="1.0" encoding="UTF-8"?>
<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_3.xsd"
id="WebApp_ID" version="2.3">
  <display-name>Archetype Created Web Application</display-name>
<!-- Spring和mybatis的配置文件 -->
<context-param> 
    <param-name>contextConfigLocation</param-name> 
    <param-value>classpath:config/*.xml</param-value> 
</context-param>
<!-- 编码过滤器 -->
<filter>
    <filter-name>encodingFilter</filter-name>
    <filter-class>org.springframework.web.filter.CharacterEncodingFilter
    </filter-class>
    <async-supported>true</async-supported>
    <init-param>
        <param-name>encoding</param-name>
        <param-value>UTF-8</param-value>
    </init-param>
</filter>
<filter-mapping>
    <filter-name>encodingFilter</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>
<!-- Spring监听器 -->
<listener>  
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>  
</listener>    
<!-- Spring MVC servlet -->
<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:config/spring-mvc.xml</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
    <async-supported>true</async-supported>
</servlet>
<servlet-mapping>
    <servlet-name>SpringMVC</servlet-name>
    <url-pattern>/</url-pattern>
</servlet-mapping>
<welcome-file-list>
    <!-- 项目启动的初始页面-->
    <welcome-file>/index.jsp</welcome-file>
</welcome-file-list>
</web-app>

到此为止就是集合完成。正常编写一个页面试试。

整体文件编写结构以及示例controller编写
返回的"hello/index"; 表明jsp文件:"/WEB-INF/views/hello/index.jsp";
JSP文件位置
访问http://localhost:8080/ssm2/hello/index效果。
访问测试controller效果图

本篇笔记到此为止结束。好记心不如烂笔头。坚持记笔记。
