新手入门——使用maven整合SSm框架

步骤1： 使用webapp骨架创建一个Maven项目。

步骤2：数据库中存放数据，为测试做准备

DROP TABLE IF EXISTS `items`;

CREATE TABLE `items` (
  `id` int(10) NOT NULL AUTO_INCREMENT,
  `name` varchar(20) DEFAULT NULL,
  `price` float(10,0) DEFAULT NULL,
  `pic` varchar(40) DEFAULT NULL,
  `createtime` datetime DEFAULT NULL,
  `detail` varchar(200) DEFAULT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=9 DEFAULT CHARSET=utf8;

/*Data for the table `items` */

insert  into `items`(`id`,`name`,`price`,`pic`,`createtime`,`detail`) values (1,‘张三‘,1000,NULL,‘2018-03-13 09:29:30‘,‘你好世界‘),(2,‘李四‘,299,NULL,‘2018-03-28 10:05:52‘,‘插入测试‘),(3,‘赵六‘,199,NULL,‘2018-03-07 10:08:04‘,‘你好赵六‘),(4,‘王五‘,100,NULL,‘2019-05-10 15:09:17‘,‘你好王五‘);

步骤三：封装实体类，创建Domain层，创建实体类Items

package com.songyoulian.domain;

import java.util.Date;

/**
 * @Author :  zhuhuicong
 * 2019/5/30  15:23
 * @Version 1.0
 */
public class Items {
    private Integer id;
    private String name;
    private Double price;
    private String pic;
    private Date createtime;
    private String detail;

    public Integer getId() {
        return id;
    }

    public void setId(Integer id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public Double getPrice() {
        return price;
    }

    public void setPrice(Double price) {
        this.price = price;
    }

    public String getPic() {
        return pic;
    }

    public void setPic(String pic) {
        this.pic = pic;
    }

    public Date getCreatetime() {
        return createtime;
    }

    public void setCreatetime(Date createtime) {
        this.createtime = createtime;
    }

    public String getDetail() {
        return detail;
    }

    public void setDetail(String detail) {
        this.detail = detail;
    }

    @Override
    public String toString() {
        return "Items{" +
                "id=" + id +
                ", name=‘" + name + ‘\‘‘ +
                ", price=" + price +
                ", pic=‘" + pic + ‘\‘‘ +
                ", createtime=" + createtime +
                ", detail=‘" + detail + ‘\‘‘ +
                ‘}‘;
    }
}

步骤4：创建Dao层，创建接口ItemsDao 。使用注解开发。

package com.songyoulian.dao;

import com.songyoulian.domain.Items;
import org.apache.ibatis.annotations.Select;

/**
 * @Author :  zhuhuicong
 * 2019/5/30  15:26
 * @Version 1.0
 */
public interface ItemsDao {
    @Select("select * from items where id = #{id}")
    public Items findById(Integer id);
}

步骤5：创建Service层，创建接口ItemsService以及其实现类ItemsServiceImpl。

package com.songyoulian.service;

import com.songyoulian.domain.Items;

/**
 * @Author :  zhuhuicong
 * 2019/5/30  15:45
 * @Version 1.0
 */
public interface ItemsService {
    public Items findById(Integer id);
}

package com.songyoulian.service.Impl;

import com.songyoulian.dao.ItemsDao;
import com.songyoulian.domain.Items;
import com.songyoulian.service.ItemsService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;

/**
 * @Author :  zhuhuicong
 * 2019/5/30  15:46
 * @Version 1.0
 */
@Service
@Transactional
public class ItemsServiceImpl implements ItemsService {

    @Autowired
    private ItemsDao itemsDao;

    @Override
    public Items findById(Integer id) {
        return itemsDao.findById(id);
    }
}

步骤6：在Resources下创建配置文件applicationContext.xml，配置Dao层和Service层相关的SpringXml配置。

<?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:aop="http://www.springframework.org/schema/aop"
       xmlns:tx="http://www.springframework.org/schema/tx"
       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/aop
                http://www.springframework.org/schema/aop/spring-aop.xsd
                http://www.springframework.org/schema/tx
                http://www.springframework.org/schema/tx/spring-tx.xsd
                http://www.springframework.org/schema/mvc
                http://www.springframework.org/schema/mvc/spring-mvc.xsd">
    <!--Dao层配置的开始-->
    <!--1配置一个数据源-->
    <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
        <property name="driverClass" value="com.mysql.jdbc.Driver"></property>
        <property name="jdbcUrl" value="jdbc:mysql:///maven"></property>
        <property name="user" value="root"></property>
        <property name="password" value="root"></property>
    </bean>
    <!--2创建一个生产SQLSession对象的工厂SQLSessionFactory对象-->
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <!--引入数据源-->
        <property name="dataSource" ref="dataSource"></property>
        <!--给pojo起别名-->
        <property name="typeAliasesPackage" value="com.songyoulian.domain"></property>
    </bean>
    <!--3对Dao层的接口包进行扫描，使用SQLSession对象给其创建代理对象，并且将创建的对象放在IOC容器中-->
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="basePackage" value="com.songyoulian.dao"></property>
    </bean>
    <!--Dao层配置的结束-->

    <!--Service层配置开始-->
    <!--1组件扫面ervice层-->
    <context:component-scan base-package="com.songyoulian.service"></context:component-scan>
    <!--2配置事务管理器-->
    <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <!--注入连接池-->
        <property name="dataSource" ref="dataSource"></property>
    </bean>
    <!--3开启事务注解的支持-->
    <tx:annotation-driven/>
    <!--Service层配置结束-->
</beans>

步骤7：创建Controller层，ItemsController.java

package com.songyoulian.controller;

import com.songyoulian.domain.Items;
import com.songyoulian.service.ItemsService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;

/**
 * @Author :  zhuhuicong
 * 2019/5/30  16:02
 * @Version 1.0
 */
@Controller
@RequestMapping("/items")
public class ItemsController {
    @Autowired
    private ItemsService itemsService;

    @RequestMapping("/show")
    public String show(Model model){
        Items items = itemsService.findById(1);
        model.addAttribute("item",items);
        return "itemDetail";
    }
}

步骤8：在Resources下创建配置文件springmvc.xml，配置Controller下的相关SpringXml配置

<?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:aop="http://www.springframework.org/schema/aop"
       xmlns:tx="http://www.springframework.org/schema/tx"
       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/aop
                http://www.springframework.org/schema/aop/spring-aop.xsd
                http://www.springframework.org/schema/tx
                http://www.springframework.org/schema/tx/spring-tx.xsd
                http://www.springframework.org/schema/mvc
                http://www.springframework.org/schema/mvc/spring-mvc.xsd">
    <!--1组件扫描-->
    <context:component-scan base-package="com.songyoulian.controller"></context:component-scan>
    <!--2开启注解-->
    <mvc:annotation-driven/>
    <!--3视图解析器-->
    <bean id="internalResourceViewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/pages/"></property>
        <property name="suffix" value=".jsp"></property>
    </bean>
    <!--4释放静态资源-->
    <mvc:default-servlet-handler></mvc:default-servlet-handler>
</beans>

步骤9：在web.xml配置中文编码过滤等

<!DOCTYPE web-app PUBLIC
        "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
        "http://java.sun.com/dtd/web-app_2_3.dtd" >
<web-app 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_3_0.xsd"
         version="3.0">
  <display-name>Archetype Created Web Application</display-name>

  <!--设置中文乱码的过滤器-->
    <filter>
        <filter-name>encodingFilter</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>encodingFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

    <!--前端控制器-->
    <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>

    <!--springmvc核心监听器-->
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:applicationContext.xml</param-value>
    </context-param>

</web-app>

步骤10：对应springmvc配置的视图解析器，在相对应的地方添加页面。itemDetail.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<%@ taglib uri="http://java.sun.com/jsp/jstl/fmt"  prefix="fmt"%>    

<!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>Insert title here</title>
</head>
<body>
    <form>
        <table width="100%" border=1>
            <tr>
                <td>商品名称</td>
                <td> ${item.name } </td>
            </tr>
            <tr>
                <td>商品价格</td>
                <td> ${item.price } </td>
            </tr>
            <tr>
                <td>生成日期</td>
                <td> <fmt:formatDate value="${item.createtime}" pattern="yyyy-MM-dd HH:mm:ss"/> </td>
            </tr>
            <tr>
                <td>商品简介</td>
                <td>${item.detail} </td>
            </tr>
        </table>
    </form>
</body>
</html>

其中，pom文件的代码如下所示，里面锁定了jar包的版本，以及配置了tomcat插件等信息

<?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"

可以启动tomcat进行测试了，启动成功后，在浏览器上访问http://localhost:8080/maven_ssm/items/show地址即可访问，可以添加log4j进行查看运行的信息

# Set root category priority to INFO and its only appender to CONSOLE.
#log4j.rootCategory=INFO, CONSOLE            debug   info   warn error fatal
log4j.rootCategory=debug, CONSOLE, LOGFILE

# Set the enterprise logger category to FATAL and its only appender to CONSOLE.
log4j.logger.org.apache.axis.enterprise=FATAL, CONSOLE

# CONSOLE is set to be a ConsoleAppender using a PatternLayout.
log4j.appender.CONSOLE=org.apache.log4j.ConsoleAppender
log4j.appender.CONSOLE.layout=org.apache.log4j.PatternLayout
log4j.appender.CONSOLE.layout.ConversionPattern=%d{ISO8601} %-6r [%15.15t] %-5p %30.30c %x - %m\n

# LOGFILE is set to be a File appender using a PatternLayout.
log4j.appender.LOGFILE=org.apache.log4j.FileAppender
log4j.appender.LOGFILE.File=d:\axis.log

新手入门——使用maven整合SSm框架的相关文章

日常开发系列——Maven+Spring+Spring MVC+MyBatis+MySQL整合SSM框架

进入公司开发已经3个多月了,项目用的是Maven+Spring+Spring MVC+MyBatis+MySQL,趁这个周末有空,仔细研读一下公司项目的基本框架,学习一下这个环境是怎么搭建起来的,经过自己的研究终于是成功地试验出来.自己亲手做的才算是自己学到的,决定将其记录下来,以便日后查询,源码同时也欢迎大家拍砖. 一.数据库的准备 这次整合试验想着做个简单的,就决定做一个普通的用户登陆,就一张表吧 我新建的数据库名字是test,然后新建了一张表 DROP TABLE IF EXISTS `u

使用Eclipse通过Maven搭建SSM框架

一,工具说明 Eclipse版本:“Eclipse Jee 2018-12”,(因为我用的是最新的eclipse,该版本已经集成了maven,所以我直接使用即可.如果你的没有Maven的话就需要安装Maven了,百度一下即可) 二,配置文件说明 pox.xml:maven依赖配置文件. dispatcher-servlet.SpringMVC配置文件. spring-config.xml  :spring配置文件 mybatis-mapper :mybatis的mapper管理配置文件 三,项目

shiro权限控制（一）：shiro介绍以及整合SSM框架

shiro安全框架是目前为止作为登录注册最常用的框架,因为它十分的强大简单,提供了认证.授权.加密和会话管理等功能 . shiro能做什么? 认证:验证用户的身份 授权:对用户执行访问控制:判断用户是否被允许做某事 会话管理:在任何环境下使用 Session API,即使没有 Web 或EJB 容器. 加密:以更简洁易用的方式使用加密功能,保护或隐藏数据防止被偷窥 Realms:聚集一个或多个用户安全数据的数据源 单点登录(SSO)功能. 为没有关联到登录的用户启用 "Remember Me&q

使用maven搭建ssm框架的javaweb项目

目前主流的javawe项目,常会用到ssm(Spring+Spring MVC+Mybatis)框架来搭建项目的主体框架,本篇介绍搭建SSM矿建的maven项目的实施流程.记之共享! 一.SSM框架介绍 SSM框架是指:Spring+Spring MVC+Mybatis. [Spring] 轻量--从大小与开销两方面而言Spring都是轻量的,此外,Spring是非侵入式的:典型地,Spring应用中的对象不依赖于Spring的特定类.简单说就是自己需要什么就导入对应的jar的即可,而不是侵入式

Maven项目搭建（二）：Maven搭建SSM框架

        上一章给大家讲解了如何使用Maven搭建web项目.       这次给大家介绍一下怎么使用Maven搭建SSM框架项目.       首先我们来看一下pom.xml的属性介绍: project: pom的xml根元素. parent:  声明继承. modules:  声明聚合,该值是一个当前POM的相对目录.用户项目的聚合. groupId:  定义当前Maven项目隶属的实际项目. artifactId:  定义实际项目中的一个Maven项目模块,一般为实际项目名称. ve

Maven创建Web项目、、、整合SSM框架

自己接触ssm框架有一段时间了,从最早的接触新版ITOO项目的(SSM/H+Dobbu zk),再到自己近期来学习到的<淘淘商城>一个ssm框架的电商项目.用过,但是还真的没有自己搭建过,一直都是用别人搭建好的.所以,从网上找了一些材料,结合自己来解决过程中的一些问题,使自己对ssm框架理解更加深了,不为分享,只是总结一下,下次有机会再搭建的时候,直接看自己的博客,省得找了! 一.准备环境: maven:apache-maven-3.2.3 jdk:jdk1.8.0_25 tomcat:tom

Maven 搭建 SSM框架——Spring+SpringMVC+Mybatis的搭建教程

一:概述 SSM框架在项目开发中经常使用到,相比于SSH框架,它在仅几年的开发中运用的更加广泛. Spring作为一个轻量级的框架,有很多的拓展功能,最主要的我们一般项目使用的就是IOC和AOP.SpringMVC是Spring实现的一个Web层,相当于Struts的框架,但是比Struts更加灵活和强大!Mybatis是 一个持久层的框架,在使用上相比Hibernate更加灵活,可以控制sql的编写,使用 XML或注解进行相关的配置!根据上面的描述,学习SSM框架就非常的重要了! 二:搭建一个
