用Maven搭建SSM框架

1.新建Maven工程，需要注意的是：在Archetype上，选择Artifact Id为maven-archetype-webapp的那项。

2.第一次构建Maven项目，会下载一些JAR包，由于Maven中央仓库速度太慢，我们选择阿里的镜像，在%MAVEN_HOME%/conf/settings.xml里，添加如下信息：（可选配置Maven本地仓库的地址。同样是在settings.xml里添加D:\Repositories\Maven）

除非你想每次下载JAR包都很慢，否则还是配置吧...

3.在Build Path里添加Tomcat的JAR包支持。成功之后的工程项目结构如图所示：

4.此时，已可以在Tomcat v8.5 Server at localhost里添加Guaipangpang项目，输入http://localhost:8080/Guaipangpang。如下图所示：

5.此时可以开始添加Spring，SpringMVC，Mybatis，MySQL，Druid，Log4j等支持。pom.xml依赖如下所示：

pom.xml

    
        
            junit
            junit
            3.8.1
            test
        
        
            org.apache.maven.plugins
            maven-resources-plugin
            2.4.3
        

        
            org.mybatis
            mybatis
            3.2.1
        
        
            org.mybatis
            mybatis-spring
            1.2.3
        
        
            org.springframework
            spring-context
            4.1.3.RELEASE
        
        
            org.springframework
            spring-beans
            4.1.3.RELEASE
        
        
            org.springframework
            spring-webmvc
            4.1.3.RELEASE
        
        
            org.springframework
            spring-jdbc
            4.1.3.RELEASE
        
        
            org.springframework
            spring-aspects
            4.1.3.RELEASE
        
        
            mysql
            mysql-connector-java
            5.0.8
        
        
            com.alibaba
            druid
            1.0.16
        
        
            javax.servlet
            jstl
            1.2
        
        
            log4j
            log4j
            1.2.16
        
        
            org.slf4j
            slf4j-api
            1.6.1
        
        
            org.slf4j
            slf4j-nop
            1.6.4
        

    

6.修改src/main/java/webapp/WEB-INF/web.xml

web.xml

    webMaven
    
    
        characterEncodingFilter
        org.springframework.web.filter.CharacterEncodingFilter
        
            encoding
            UTF-8
        
    
    
        characterEncodingFilter
        /*
    

    
    
        contextConfigLocation
        classpath:spring.xml,classpath:mybatis-spring.xml
    
    
    
        org.springframework.web.context.ContextLoaderListener
    

    
    
        springDispatcherServlet
        org.springframework.web.servlet.DispatcherServlet
        
            contextConfigLocation
            classpath:spring-mvc.xml
        
        1
    
    
        springDispatcherServlet
        /
    

    
        index.html
        index.jsp
    

7.在src/main/resources下添加配置文件：

spring.xml

mybatis-spring.xml

spring-mvc.xml

mybatis-config.xml

log4j.properties

log4j.rootLogger=DEBUG, stdout
log4j.logger.org.mybatis=DEBUG
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%5p %d %C: %m%n

mysqldb.properties

jdbc.driverClassName=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://192.168.0.106:3306/test
jdbc.username=root
jdbc.password=root

8.Java文件与JSP文件如下所示：

PersonController

package com.gpp.controller;

import java.util.List;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;

import com.gpp.model.Person;
import com.gpp.service.IPersonService;

@Controller
@RequestMapping("/personController")
public class PersonController {
    
    private IPersonService personService;
    
    public IPersonService getPersonService() {
        return personService;
    }

    @Autowired
    public void setPersonService(IPersonService personService) {
        this.personService = personService;
    }

    @RequestMapping("/showPerson")
    public String showPersons(Model model){
        List persons = personService.loadPersons();
        model.addAttribute("persons", persons);
        return "showperson";
    }
}

PersonMapper

package com.gpp.dao;

import java.util.List;

import com.gpp.model.Person;

public interface PersonMapper {
    /**
     * 插入一条记录
     * @param person
     */
    void insert(Person person);
    
    /**
     * 查询所有
     * @return
     */
    List queryAll();
}

PersonMapper

 

      
      
        select * from person  
    

Person.java

package com.gpp.model;

/**
 * person 实体
 * @author Administrator
 *
 */
public class Person {

    private int id;
    private String name;
    private int age;
    
    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 int getAge() {
        return age;
    }
    public void setAge(int age) {
        this.age = age;
    }
    
    @Override
    public String toString() {
        return "Person [id=" + id + ", name=" + name + "]";
    }
}

IPersonService

package com.gpp.service;

import java.util.List;

import com.gpp.model.Person;

public interface IPersonService {

    /**
     * 加载全部的person
     * @return
     */
    List loadPersons();
}

PersonServiceImpl

package com.gpp.service.impl;

import java.util.List;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import com.gpp.dao.PersonMapper;
import com.gpp.model.Person;
import com.gpp.service.IPersonService;

@Service("personService")
public class PersonServiceImpl implements IPersonService {
    
    private PersonMapper personMapper;

    public PersonMapper getPersonMapper() {
        return personMapper;
    }
    @Autowired
    public void setPersonMapper(PersonMapper personMapper) {
        this.personMapper = personMapper;
    }
    
    public List loadPersons() {
        return personMapper.queryAll();
    }

    
}

9.项目结构如图所示：

11.输入http://localhost:8080/Guaipangpang/personController/showPerson。
即可得到如下所示的结果：

12.至此，由Maven搭建SSM框架正式完成。
