陌上花开
等风来

0、系统环境

1)Windows 10 企业版

2)JDK 1.8.0_131

3)Eclipse Java EE IDE for Web Developers  Version: Neon.3 Release (4.6.3)

4)Tomcat 8.5

 

1、maven下载及配置

maven的下载地址:http://maven.apache.org/download.cgi

下载后解压放在d:\Java路径下 

在环境变量中,新增系统变量名:MAVEN_HOME,变量值:D:\Java\maven

在Path中追加:%MAVEN_HOME%\bin;

在命令行窗口中输入:mvn –v,如果看见下图则说明maven安装配置完毕

2、maven仓库的设置

maven仓库默认位置在系统用户目录下的.m2目录中,类似下图

因为众所周知的原因,直接访问maven公共仓库的速度比较慢,所以推荐使用阿里的maven仓库镜像。编辑setting.xml文件,在mirrors节点下,新增如下内容,这样从仓库中下载jar包速度上会快很多。

<mirror>
       <id>nexus-aliyun</id>
       <mirrorOf>*</mirrorOf>
       <name>Nexus aliyun</name>
<url>http://maven.aliyun.com/nexus/content/groups/public</url> </mirror>

 

3、eclipse整合maven

设置eclipse自带maven整合工具,在Preferences中找到Maven节点,观察User Settings项的设置是否正确

点击Installations节点,添加maven runtime

 

4、创建maven项目时设置JDK

问题描述:eclipse创建maven项目时,显示的JDK默认版本为1.5,实际使用的JDK为1.8,如何修改?

解决方案:找到本机maven仓库存放位置,比如:${user.home}/.m2/路径,编辑settings.xml文件,在profiles节点下配置

复制代码
<profile>

    <id>jdk-1.8</id>

    <activation>

        <activeByDefault>true</activeByDefault>

        <jdk>1.8</jdk>

    </activation>

    <properties>

        <maven.compiler.source>1.8</maven.compiler.source>

        <maven.compiler.target>1.8</maven.compiler.target>

        <maven.compiler.compilerVersion>1.8</maven.compiler.compilerVersion>

    </properties>

</profile>
复制代码

 

5、使用maven创建SSM项目

1)选择Maven Project

2)点击Next,选择默认工作空间位置

3)选择web类型

4)填写GroupID、ArtifactID

Group ID:相当于一个组织

Artifact ID:相当于这个组织下的一个具体项目

Packege:根据Group ID和Artifact ID生成一个默认的名称

5)创建出的maven项目如下图

6)问题描述:提示错误:

在eclipse中设置Server为Tomcat,注意JRE设置为安装的JDK的jre

在工程上右键,查看工程属性,找到Java Build Path,添加Server Runtime为Tomcat

 

点击Finish后,项目工程变为下图

7)在项目上右键,查看项目信息

默认的Dynamic Web Module为2.3,使用Tomcat 8.5,需要修改为3.1

修改方法:

① maven工程所在目录下org.eclipse.wst.common.project.facet.core.xml

编辑内容,如下所示

复制代码
<?xml version="1.0" encoding="UTF-8"?>

<faceted-project>

  <fixed facet="wst.jsdt.web"/>

  <installed facet="java" version="1.8"/>

  <installed facet="jst.web" version="2.3"/>

  <installed facet="wst.jsdt.web" version="1.0"/>

</faceted-project>
复制代码

改为

复制代码
<?xml version="1.0" encoding="UTF-8"?>

<faceted-project>

  <fixed facet="wst.jsdt.web"/>

  <installed facet="java" version="1.8"/>

  <installed facet="jst.web" version="3.1"/>

  <installed facet="wst.jsdt.web" version="1.0"/>

</faceted-project>
复制代码

② maven工程下的web.xml文件修改为

<?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_3_1.xsd"
       version="3.1" metadata-complete="true">
</web-app>

③ pom.xml文件中修改build节点,添加如下内容

复制代码
<plugins>
       <plugin>
              <groupId>org.apache.maven.plugins</groupId>
              <artifactId>maven-compiler-plugin</artifactId>
              <configuration>
                     <source>1.8</source>
                     <target>1.8</target>
              </configuration>
       </plugin>
</plugins>
复制代码

④ 修改后,在项目上右键,找到Maven属性下的Update Project,点击之

 

⑤ 选择该项目进行更新,如果怕不能强制更新,可以勾选Force Update of Snapshots/Releases

⑥ 点击OK后更新maven项目,再观察项目属性,Module已经变为3.1

 

6、下载ssm框架所需jar包

修改pom.xml内容为:

复制代码
<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/maven-v4_0_0.xsd">

            </plugin>
        </plugins>
    </build>
</project>
复制代码

保存后,可以看到相关jar包被下载至本地仓库 

7、完善项目结构

因为服务端maven项目的标准结构有四个子包:src/main/java、src/main/resources、src/test/java、src/test/resources,这里缺少了src/test/resources,所以手动补上。

在项目中新建Source Folder

创建src/test/resources目录后,工程如下图所示

右键查看项目属性,点击Deployment Assembly,移除test和target

移除后如下图

 

8、创建项目用的配置文件

创建log4j.properties文件,内容如下:

复制代码
#USE THIS SETTING FOR OUTPUT MYBATIS`s SQL ON THE CONSOLE
log4j.rootLogger=DEBUG, Console

#Console
log4j.appender.Console=org.apache.log4j.ConsoleAppender
log4j.appender.Console.layout=org.apache.log4j.PatternLayout
log4j.appender.Console.layout.ConversionPattern=%d [%t] %-5p [%c] - %m%n

log4j.logger.java.sql.ResultSet=INFO
log4j.logger.org.apache=INFO
log4j.logger.java.sql.Connection=DEBUG
log4j.logger.java.sql.Statement=DEBUG
log4j.logger.java.sql.PreparedStatement=DEBUG
复制代码

 

创建mybatis-config.xml文件,内容如下:

复制代码
<?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>
    <!-- 设置别名 -->
    <typeAliases>
        <package name="cn.temptation.domain" />
    </typeAliases>
</configuration>
复制代码

 

创建spring-mvc.xml文件,内容如下:

复制代码
<?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"

    <!-- 注册MVC注解驱动 -->
    <mvc:annotation-driven />

    <!-- 静态资源可访问的设置方式 -->
    <mvc:default-servlet-handler />

    <!-- 配置视图解析器,可以显式设置,也可以不设置,不设置会依据SpringMVC的默认设置 -->
    <bean id="viewResolver"
        class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/" />
        <property name="suffix" value=".jsp" />
    </bean>
</beans>
复制代码

 

创建spring-mybatis.xml文件,内容如下:

 

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

    <!-- 定义数据源Bean -->
    <!-- Druid -->
    <bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource">
        <property name="url" value="jdbc:mysql://localhost:3306/test" />
        <property name="username" value="root" />
        <property name="password" value="sa" />
    </bean>

    <!-- 注册SqlSessionFactoryBean -->
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">

        <!-- 自动扫描mappers.xml文件 -->
        <property name="mapperLocations" value="classpath:cn/temptation/dao/*.xml" />
        <property name="configLocation" value="classpath:mybatis-config.xml"></property>
    </bean>
    
    <!-- DAO接口所在包名,Spring会自动查找其下的类 -->
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="basePackage" value="cn.temptation.dao" />
        <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory" />
    </bean>
</beans>
复制代码

 

 

创建spring-tx.xml文件,内容如下:

 

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

        <aop:advisor advice-ref="txAdvice" pointcut="within(cn.temptation.web..*)" />
    </aop:config>
</beans>
复制代码

 

 

9、编写服务端代码

编写User实体类,代码如下:

复制代码
package cn.temptation.domain;

/**
 * 用户信息
 */
public class User {
    // 成员变量
    private Integer userid;
    private String username;
    private String password;

    // 构造函数
    public User() {
        super();
    }

    public User(Integer userid, String username, String password) {
        super();
        this.userid = userid;
        this.username = username;
        this.password = password;
    }

    // 成员方法
    public Integer getUserid() {
        return userid;
    }

    public void setUserid(Integer userid) {
        this.userid = userid;
    }

    public String getUsername() {
        return username;
    }

    public void setUsername(String username) {
        this.username = username;
    }

    public String getPassword() {
        return password;
    }

    public void setPassword(String password) {
        this.password = password;
    }
}
复制代码

 

编写UserController控制器,代码如下:

复制代码
package cn.temptation.web;

import javax.annotation.Resource;
import javax.servlet.http.HttpSession;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.servlet.ModelAndView;

import cn.temptation.dao.UserDao;
import cn.temptation.domain.User;

/**
 * 用户控制器
 */
@Controller
@RequestMapping(value = "/user")
public class UserController {
    @Resource
    private UserDao userDao;

    @RequestMapping("/view")
    public String view() {
        return "main/login";
    }

    @RequestMapping("/indexview")
    public String index() {
        return "main/index";
    }

    @RequestMapping(value = "/login", method = RequestMethod.POST)
    public ModelAndView login(User model, HttpSession session) {
        User user = userDao.findByUsername(model.getUsername());

        if (user == null || !user.getPassword().equals(model.getPassword())) {
            return new ModelAndView("redirect:/login.jsp");
        } else {
            session.setAttribute("user", user);
            ModelAndView mav = new ModelAndView();
            mav.setViewName("index");
            return mav;
        }
    }
}
复制代码

 

编写UserDao数据访问层接口,代码如下:

复制代码
package cn.temptation.dao;

import cn.temptation.domain.User;

public interface UserDao {
    public abstract User findByUsername(String username);
}
复制代码

 

编写UserMapper.xml数据访问层映射文件,代码如下:

 

复制代码
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
        "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="cn.temptation.dao.UserDao">
    <select id="findByUsername" parameterType="string" resultType="User">
        SELECT * FROM userinfo WHERE username=#{username}
    </select>
</mapper>
复制代码

 

 

10、编写客户端代码

 

编写login.jsp登录页,代码如下:

复制代码
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>登录</title>
</head>
<body>
<form action="user/login" method="post">
<label>账号:</label>
<input type="text" id="txtUsername" name="username" placeholder="请输入账号" /><br/>
<label>密码:</label>
<input type="password" id="txtPassword" name="password" placeholder="请输入密码" /><br/>
<input type="submit" value="提交" />
<input type="reset" value="重置" />
</form>
</body>
</html>
复制代码

 

编写index.jsp主页,代码如下:

复制代码
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>主页</title>
</head>
<body>
<h3>欢迎,${user.username }</h3>
</body>
</html>
复制代码

 

 

11、使用maven构建项目

在项目上右键,找到Maven属性的Update Project,也可以Alt+F5操作

 

修改项目编译路径为JRE系统类库,否则后续操作出错

项目上右键,找到Run As属性,找到Maven install

点击执行,结果如下说明构建成功

项目运行还是使用web工程的部署运行方式

运行项目,观察是否报错

登录页面

登录成功,跳转到主页
