项目背景:使用IDEA搭建Maven WEB项目

项目架构:Spring、Spring MVC、 Mybatis、Mysql/Oracle、Layui

项目环境:Windows x64

-------------------------------------------------------------神奇的分隔符------------------------------------------------------------------------------------------前言:使用IDEA开发工具、本地Maven必须正确配置完成

一、开始创建maven web项目

IDEA、Maven、Spring、Spring MVC、Mybatis、Layui
搭建maven项目

 

 

IDEA、Maven、Spring、Spring MVC、Mybatis、Layui
创建项目
IDEA、Maven、Spring、Spring MVC、Mybatis、Layui
Maven配置(maven home directory:本地maven安装路径,User setting file:maven setting配置, Local repository:maven 本地仓库配置)

 

project:项目名称;project location:项目存放路径(IDEA工作空间)

然后点击 Finsh

IDEA、Maven、Spring、Spring MVC、Mybatis、Layui

 

等待maven加载插件和配置文件;点击 import  changes下载项目依赖

IDEA、Maven、Spring、Spring MVC、Mybatis、Layui
进度条在加载,等待加载完成

 

 二、配置项目结构

         项目加载完成,左侧会显示项目结构,需要新建两个文件夹、一个是java文件夹、一个是resources文件夹

        点击 file----->project  structure----->modules

IDEA、Maven、Spring、Spring MVC、Mybatis、Layui
新建java文件夹、新建resources文件夹

 

 new folder(创建两个文件夹,java和resources)

IDEA、Maven、Spring、Spring MVC、Mybatis、Layui
src/main/java,src/main/resources

 

 创建完成如下,并给java和resource分配相应的文件夹属性

IDEA、Maven、Spring、Spring MVC、Mybatis、Layui
java、resource文件夹创建

 

选择artifacts--------->点击中间的那个"+"号--------->Web application:exploded-------->from modules----->ByyWebDemo:war exploded------>Apply---->OK

IDEA、Maven、Spring、Spring MVC、Mybatis、Layui

 

配置完成后的项目结构如下:

IDEA、Maven、Spring、Spring MVC、Mybatis、Layui

 

三、配置tomcat

选择Run--->Edit  Configurations------->选择"+"号----->Tomcat Server---->Local

IDEA、Maven、Spring、Spring MVC、Mybatis、Layui

server(tomcat配置)------>deployment (项目war包)

选择带有 :war exploded的包

IDEA、Maven、Spring、Spring MVC、Mybatis、LayuiIDEA、Maven、Spring、Spring MVC、Mybatis、Layui

四、启动tomcat

启动项目,测试项目是否能够正常启动(正常启动如下图)

IDEA、Maven、Spring、Spring MVC、Mybatis、Layui

浏览器会自动弹出启动后、访问的首页(项目正常启动)

IDEA、Maven、Spring、Spring MVC、Mybatis、Layui

五、pom.xml中引入必要的依赖

<properties>
  <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
  <maven.compiler.source>1.7</maven.compiler.source>
  <maven.compiler.target>1.7</maven.compiler.target>
  <!-- 配置相关jar包的版本 -->

六、新建数据库配置jdbc.yml文件、日志记录log4j.properties文件

IDEA、Maven、Spring、Spring MVC、Mybatis、Layui               IDEA、Maven、Spring、Spring MVC、Mybatis、Layui               

 

 jdbc.yml:

jdbc.driver=oracle.jdbc.driver.OracleDriver

jdbc.url=jdbc:oracle:thin:@localhost:1521:orcl

jdbc.username=test

jdbc.password=test1
  #定义初始连接数
initialSize=0
  #定义最大连接数
maxActive=20
  #定义最大空闲
maxIdle=20
  #定义最小空闲
minIdle=1
  #定义最长等待时间
maxWait=60000

log4j.properties

log4j.rootLogger=INFO,Console,File

  #控制台日志
log4j.appender.Console=org.apache.log4j.ConsoleAppender
log4j.appender.Console.Target=System.out
log4j.appender.Console.layout=org.apache.log4j.PatternLayout
log4j.appender.Console.layout.ConversionPattern=[%p][%t][%d{yyyy-MM-dd HH\:mm\:ss}][%C] - %m%n

  #普通文件日志
log4j.appender.File=org.apache.log4j.RollingFileAppender
log4j.appender.File.File=logs/ssm.log
log4j.appender.File.MaxFileSize=10MB
  #输出日志,如果换成DEBUG表示输出DEBUG以上级别日志
log4j.appender.File.Threshold=ALL
log4j.appender.File.layout=org.apache.log4j.PatternLayout
log4j.appender.File.layout.ConversionPattern=[%p][%t][%d{yyyy-MM-dd HH\:mm\:ss}][%C] - %m%n

七、新建spring-mybatis.xml整合文件,spring-mvc.xml文件

(1)在resource文件夹下新建spring-mybatis.xml

    <!-- 一、配置事务管理器-->
    <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <property name="dataSource" ref="dataSource"/>
    </bean>

    <!-- 二、开启注解事务 (Spring框架的事务管理之基于AspectJ的注解方式)-->
    <tx:annotation-driven transaction-manager="transactionManager"/>

            <tx:method name="count*" read-only="true"/>
            <!-- 对其他方法 使用默认的事务管理 -->
            <tx:method name="*"/>
        </tx:attributes>
    </tx:advice>

    <!-- 配置使Spring采用CGLIB代理 -->
    <aop:aspectj-autoproxy proxy-target-class="true"/>
</beans>

(2)在resource文件夹下新建spring-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: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/mvc/spring-mvc-4.0.xsd">

    <!-- 自动扫描  @Controller-->
    <context:component-scan base-package="com.byy.controller"/>

    <!-- 默认的注解映射 -->
    <mvc:annotation-driven />

    <!-- 解除servlet对静态资源文件访问的限制,使得静态资源先经过 -->
    <!--<mvc:default-servlet-handler />-->

    <mvc:resources location="/static/"  mapping="/static/**"  />

    <!--避免IE执行AJAX时,下载JSON文件的现象 -->
    <bean id="mappingJacksonHttpMessageConverter"
          class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">
        <property name="supportedMediaTypes">
            <list>
                <value>text/html;charset=UTF-8</value>
                <value>text/json;charset=UTF-8</value>
                <value>application/json;charset=UTF-8</value>

        <property name="messageConverters">
            <list>
                <ref bean="mappingJacksonHttpMessageConverter"/> <!-- JSON转换器 -->

        <property name="prefix" value="/WEB-INF/jsp/" />
        <property name="suffix" value=".jsp" />
    </bean>

</beans>

八、配置web.xml文件

<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
    http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">

  <!-- 设置Spring容器加载配置文件的路径 -->
  <context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath:spring-mybatis.xml</param-value>
  </context-param>
  
  <!--解决POST乱码问题-->
  <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>forceEncoding</param-name>
      <param-value>true</param-value>
    </init-param>
  </filter>
  <filter-mapping>
    <filter-name>CharacterEncodingFilter</filter-name>
    <url-pattern>/*</url-pattern>
  </filter-mapping>

  <!-- Spring监听器 -->
  <listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>

  <!-- 防止Spring内存溢出监听器 -->
  <listener>
    <listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class>
  </listener>

  <!--springmvc前端控制器配置-->
  <servlet>
    <servlet-name>dispatcherServlet</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
      <param-name>contextConfigLocation</param-name>
      <param-value>classpath*:spring-mvc.xml</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
  </servlet>

  <servlet-mapping>
    <servlet-name>dispatcherServlet</servlet-name>
    <url-pattern>/</url-pattern>
  </servlet-mapping>
</web-app>

九、启动tomcat,查看web服务是否正常启动

下图就是正常启动

IDEA、Maven、Spring、Spring MVC、Mybatis、Layui

 

十、配置mybatis-generator自动生成代码插件

       (1) 在pom.xml文件中添加

<plugin>
  <groupId>org.mybatis.generator</groupId>
  <artifactId>mybatis-generator-maven-plugin</artifactId>
  <version>1.3.2</version>
  <configuration>
    <configurationFile>src/main/resources/generatorConfig.xml</configurationFile>
    <verbose>true</verbose>
    <overwrite>true</overwrite>
  </configuration>
  <executions>
    <execution>
      <id>Generate MyBatis Artifacts</id>
      <goals>
        <goal>generate</goal>
      </goals>
    </execution>
  </executions>
</plugin>
<dependency>
  <groupId>org.mybatis.generator</groupId>
  <artifactId>mybatis-generator-core</artifactId>
  <version>1.3.2</version>
</dependency>

        (2)在resource下新建mapper文件夹,用户存放mybatis-generator自动生成dao层接口映射的mapper.xml文件

         (3)在resource下新建generatorConfig.xml文件,此xml文件是mybatis-generator配置文件

generatorConfig.xml内容(自己修改相应位置)

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE generatorConfiguration
        PUBLIC "-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN"
        "http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd">
<generatorConfiguration>

    <!--数据库驱动jar包的真实路径 -->
    <classPathEntry  location="D:\Maven\Repository\com\oracle\ojdbc6\11.2.0.1.0\ojdbc6-11.2.0.1.0.jar"/>

    <context id="default"  targetRuntime="MyBatis3Simple" defaultModelType="flat">

        <!-- 该插件给实体类添加toString()方法  -->
        <plugin type="org.mybatis.generator.plugins.ToStringPlugin"/>
        <!-- 这个插件给由MBG生成的Java模型对象增加了equals和hashCode方法 -->
        <plugin type="org.mybatis.generator.plugins.EqualsHashCodePlugin"/>

(4)、运行generator插件

run----->maven---->NAME(随意起名)------>Command line(mybatis-generator:generate -e )

IDEA、Maven、Spring、Spring MVC、Mybatis、Layui

 

 

生成成功

IDEA、Maven、Spring、Spring MVC、Mybatis、Layui

 

十一、前端使用layui框架

(1)在webapp下新建static文件夹存放静态文件,js、image、css等

(2)在web-inf下新建jsp文件夹,用于存放jsp文件 

IDEA、Maven、Spring、Spring MVC、Mybatis、LayuiIDEA、Maven、Spring、Spring MVC、Mybatis、Layui

在webapp-------》static-----》导入layui的css、js文件(layui的官网下载,直接放入文件夹中即可)

 

(3)在WEB-INF的jsp文件夹下新建tabledata.jsp文件,这里引入layui的样式,一个简单的ajax请求数据表格

tabledata.jsp

<!DOCTYPE html>
<html>
<head>
    <%@ page contentType="text/html;charset=utf-8" %>
    <title>layui</title>
    <meta name="renderer" content="webkit">
    <meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1">
    <meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1">
    <link rel="stylesheet" href="${pageContext.request.contextPath }/static/layui/css/layui.css"  media="all">
    <!-- 注意:如果你直接复制所有代码到本地,上述css路径需要改成你本地的 -->
</head>
<body>
<table class="layui-hide" id="test"></table>
<script src="${pageContext.request.contextPath }/static/layui/layui.js" charset="utf-8"></script>
<!-- 注意:如果你直接复制所有代码到本地,上述js路径需要改成你本地的 -->
<script>
    layui.use('table', function(){
        var table = layui.table;
        table.render({
            elem: '#test'
            ,url:'${pageContext.request.contextPath}/Byy/getAllList?userId=11111'
            ,cols: [[
                {field:'userId',  title: 'ID', sort: true}
                ,{field:'userName',title: '用户名'}
                ,{field:'userPassword',title: '密码', sort: true}
                ,{field:'userEmail',title: '邮箱'}
                ,{field:'userPhone',title: '手机'}
                ,{field:'userPhoto', title: '图片', sort: true}
            ]]
            ,page: true
        });
    });
</script>
</body>
</html>

(4)在index.jsp页面中加入a标签跳转到tabledata.jsp页面

<html>
<head>
    <%@ page contentType="text/html;charset=utf-8" %>
</head>
<body>
<h2>Hello World!</h2>
<a href="${pageContext.request.contextPath }/Byy/ByyAjax">请点击跳转</a>
</body>
</html>

(5)启动项目后访问后台数据,效果如下

IDEA、Maven、Spring、Spring MVC、Mybatis、Layui

通过控制器跳转

IDEA、Maven、Spring、Spring MVC、Mybatis、Layui

 

controller层代码

@Controller
@RequestMapping("Byy")
public class BycController {
    private static final Logger logger = LoggerFactory.getLogger(BycController.class);
    @Autowired
    private BycService bycService;
    @RequestMapping(value = "/getAllList",method = RequestMethod.GET)
    @ResponseBody
    private Map<String,Object> getAllList(@RequestParam Integer userId, HttpServletRequest request, HttpServletResponse response){
        List<Byc> lists = bycService.selAll();
        int count = bycService.getCount();
        Map<String,Object> jsonmap=new HashMap<String,Object>();
        jsonmap.put("code",0);
        jsonmap.put("data",lists);
        jsonmap.put("count",count);
        jsonmap.put("msg","查询成功");
        logger.info("===============================成功查询用户列表!");
        return jsonmap;
    }
    @RequestMapping("/ByyAjax")
    public  String ajaxByc(){
        return  "tabledata";
    }
}

十二、最终项目结构如下

IDEA、Maven、Spring、Spring MVC、Mybatis、Layui

 

自此项目正常运行,后续会加入其它模块;敬请期待
