使用maven快速搭建SSM框架实例

1.先创建工程

 2.选择idea提供好的maven的web工程模板

　　有个需要注意的细节，在创建工程的时候，添加一个参数archetypeCatalog的值为internal，这个参数会使得maven工程的依赖jar包直接从本地仓库拉取，不配置的话每次都会从maven的中央仓库拉取，网络不好会很耗时间。

 

3.然后按照步骤创建成功后，在src的main目录下创建java（放置java代码）和resources（放配置文件）目录并分别添加为source root和resources root目录，然后配置pom.xml文件，先将spring与mybatis整合，然后再加入springmvc进来

  3.1 先添加pom.xml文件中的依赖

<properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    <maven.compiler.source>1.8</maven.compiler.source>
    <maven.compiler.target>1.8</maven.compiler.target>
    <spring.version>5.0.5.RELEASE</spring.version>
    <springmvc.version>5.0.5.RELEASE</springmvc.version>
    <mybatis.version>3.4.5</mybatis.version>
  </properties>

　　如果想要添加tomcat插件到maven中，同时修改tomcat端口号为8081的话，添加以下代码到pom.xml文件的plugins标签中

<plugin>
          <groupId>org.apache.tomcat.maven</groupId>
          <artifactId>tomcat7-maven-plugin</artifactId>
          <version>2.2</version>
          <configuration>
            <port>8081</port>
            <path>/</path>
          </configuration>
        </plugin>
View Code

　　然后我们可以使用maven的tomcat插件来运行工程

  3.2 我们先创建一个数据库ssmtest，然后在里面创建商品表item

CREATE TABLE `item` (
  `id` int(11) NOT NULL auto_increment,
  `name` varchar(255) default NULL,
  `price` float default NULL,
  `createtime` datetime default NULL,
  `detail` varchar(255) default NULL,
  PRIMARY KEY  (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8
View Code

  同时加一条数据进去

  3.3 然后创建POJO类 Item

public class Item {

    private int id;
    private String name;
    private float price;
    private Date createtime;
    private String detail;

    public int getId() {
        return id;
    }

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

    public String getName() {
        return name;
    }

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

    public float getPrice() {
        return price;
    }

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

    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 "Item{" +
                "id=" + id +
                ", name='" + name + '\'' +
                ", price=" + price +
                ", createtime=" + createtime +
                ", detail='" + detail + '\'' +
                '}';
    }

}

  3.4 持久层DAO接口编写

public interface ItemMapper {
       public Item findById(int id);
}
View Code

  3.5 Mapper映射文件编写

　　ItemMapper.xml

<?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="com.atyyc.ssm.dao.ItemMapper">
<select id="findById" parameterType="int" resultType="item">
         select * from item where id=#{id}</select>
</mapper>
View Code

  3.6 业务层Service编写

　　ItemService接口

public interface ItemService {
    public Item findById(int id);

}
View Code

　　ItemServiceImpl类

@Service
@Transactional
public class ItemServiceImpl implements ItemService{

    @Autowired
    private ItemMapper itemMapper;


    @Override
    public Item findById(int id) {
        return itemMapper.findById(id);
    }
}
View Code

  3.7 先写个数据库的配置文件db.properties方便之后修改数据库，然后再进行mybatis配置文件applicationContext-dao.xml编写

　　db.properties:

jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/ssmtest
jdbc.username=root
jdbc.password=123

        model.addAttribute("item",item);
        return "item";

  3.10 加入springmvc，spring，mybatis相关配置进web.xml文件中

<!--指定Spring配置文件位置-->
<context-param>
  <param-name>contextConfigLocation</param-name>
  <param-value>classpath*:applicationContext*</param-value>
</context-param>

<!-- 配置Spring框架启动时使用的监听器-->
<listener>
  <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

<!-- 配置SpringMVC的前端控制器-->
<servlet>
  <servlet-name>springmvc</servlet-name>
  <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
  <!-- 指定springmvc配置文件-->
  <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>*.do</url-pattern>
</servlet-mapping>
View Code

　　然后编写一个item.jsp的页面放在/WEB-INF/jsp目录下，以便访问　

<%@ page contentType="text/html;charset=UTF-8" isELIgnored="false" language="java" %>
<html>
<head>
    <title>Title</title>
</head>
<body>
    ${item}
</body>
</html>
View Code

　　此时ssm配置的基本内容就结束了，然后开始部署运行。

4.部署运行

  4.1 开始配置Tomcat，点击上方的下拉框进入配置界

 

  4.2 按照图示点击添加本地tomcat服务器，点击+号，然后选择Tomcat Server，选择Local选项

   4.3 在弹出的对话框中，选择Deployment点击右侧的+号，选择Artifact

   4.4 然后回到Server选项卡，配置Tomcat的基本参数，最后点击ok即可

 

  如果tomcat在控制台输出乱码的话可以在VM options：这一选项中添加-Dfile.encoding=UTF-8即可。如果没效果，可能是因为idea的文件的编码格式不是utf-8，这些都是刚安装idea的时候就应该配置好的。如果设置了还是乱码的话，参考一下如下的博客：

https://www.jb51.net/article/175289.htm

  4.5 最后在下拉框中选中要运行的tomcat，点击右侧的运行按钮即可。

　　最后弹出如下网页才算运行成功。

  4.6 最后我们输入http://localhost:8080/hello_ssm/item/showItem/1.do  来测试一下我们写的商品类的搜索功能有没有问题，然后出现如下页面证明测试成功

 

 　　这时ssm才算初步运行起来了。
