maven搭建ssm项目

参考1：使用idea搭建maven+ssm项目

start.

第一部分：项目创建

1、在idea中，点击new project。选择maven、jdk，并从模板创建project，注意模板选择5中框中的模板（否则后续可能出现问题），点击下一步，创建project。

2、填写项目的groupid和artifactid，并点击下一步。

3、选择自己的maven目录，点击下一步

4、点击finsh，完成项目创建。

 

第二部分：项目结构

 

第三部分：项目配置文件编写

5、配置pom.xml，导入需要引用的ssm包。

6、配置web工程必须的web.xml文件

    Archetype Created Web Application

    
        contextConfigLocation
        classpath:applicationContext.xml
    
    
        log4jConfigLocation
        classpath:log4j.properties
    

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

    
    
        org.springframework.web.context.ContextLoaderListener
    
    
    
        org.springframework.web.util.IntrospectorCleanupListener
    

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

    
        /index.jsp
    

    
    
        30
    

7、配置spring（applicationContext.xml）、SpringMVC（spring-mvc.xml）、mybatis（spring-mybatis.xml）所需配置的xml文件，及其他配置文件（如：数据库信息配置config.properties、日志配置log4j.properties）。

applicationContext.xml

    
        
            
                classpath:config.properties
            
        
        
    
    
    
        
    

    

spring-mvc.xml

    
        
            
            
            
            
        
    

    
    
    

    
    
    
    
        
            
                
                
                
            
        
    

    
    
        
            
                text/html;charset=UTF-8
                application/json
            
        
        
            
                WriteMapNullValue
                QuoteFieldNames
            
        
    

    
    
        
        
    

spring-mybatis.xml

config.properties

log4j.properties

### set log levels ###

第四部分：初始化，编写简单测试代码，确认搭建成功。

8、编写jsp文件

index.jsp

<%@ page contentType="text/html;charset=UTF-8" language="java" %>


    
    
    
    
    
    




Hello World!
点击返回数据
点击返回页面

home.jsp

<%@ page contentType="text/html;charset=UTF-8" language="java" %>


    
    
    
    
    
    



第二个页面

9、编写控制层controller。

isoft/controller/TestController.java

package isoft.controller;

import com.alibaba.fastjson.JSONObject;
import isoft.service.TestService;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.ResponseBody;

@Controller
@RequestMapping("/index")
public class TestController {

    private static final Logger LOGGER = LoggerFactory.getLogger(TestController.class);

    @Autowired
    private TestService testService;

    @RequestMapping(value = "/testAction", method = RequestMethod.GET)
    @ResponseBody
    public JSONObject indexTest(String data) {

        int i = testService.testAction();
        JSONObject jsonObject = new JSONObject();
        jsonObject.put("test", i);

        return jsonObject;
    }
    
    @RequestMapping(value = "/testActionDemo2", method = RequestMethod.GET)
    public String indexTest2() {
        return "home";
    }

}

10、编写service层接口及实现类。

isoft/service/TestService.java

package isoft.service;

public interface TestService {

    int testAction();

}

isoft/service/impl/TestServiceImpl.java

package isoft.service.impl;

import isoft.dao.TestDao;
import isoft.service.TestService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

@Service
public class TestServiceImpl implements TestService {

    @Autowired
    TestDao testDao;

    @Override
    public int testAction() {
        return testDao.selectCount();
    }
}

11、编写dao层需要的接口及mapper文件。

isoft/dao/TestDao.java

package isoft.dao;

public interface TestDao {

    int selectCount();

}

mapper/test.xml

    
        select count(1) from tb_user
    

第五部分：配置Tomcat，启动、访问项目（也尝试了直接使用maven的tomcat插件方式配置可以启动的tomcat，但是配置成功之后，项目启动报错，暂时没有解决，所以先按照以下方式配置）

12、点击run-Edit Configurations

13、添加一个新的local tomcat，并配置（或选择）tomcat。

14、点击添加，将新建的项目配置关联到tomcat，然后配置访问路径为“localhost:xxxx/myssm”，点击确定保存tomcat。

15、启动项目，请求“http://localhost:8088/myssm/”，项目搭建完成，示例代码正常可用。结果如下所示：

 

第六部分：ps

之前提到的maven配置tomcat插件的方式，配置并启动tomcat，配置方式如下：

1、在pom.xml文件中配置tomcat插件引入，如下图：

2、点击run-Edit Configurations

3、配置一个maven方式的项目启动，command line填写为“clean tomcat7:run”，点击ok。

4、启动项目，完成配置。访问，查看效果。（但是目前启动的时候会报错）

ps：报错如下：
