Eclipse中使用Maven搭建SSM框架

Eclipse中不使用Maven搭建SSM框架：https://www.cnblogs.com/xuyiqing/p/9569459.html

IDEA中使用Maven搭建SSM框架：https://www.cnblogs.com/xuyiqing/p/10522339.html

 

Eclipse新建Maven Project->archetype选择webapp

Window-Preferences->搜索JRES配置本地JDK（推荐1.8，过高或过低可能出现未知问题）

Window-Preferences->搜索Maven配置本地Maven和settings.xml

Window-Preferences->搜索Server配置本都Tomcat

 

然而新建好的Maven Project是报错的

解决：选中项目右键Properties->Java Build Path->Libraries->Add Library，添加Server Runtime，应用后就不会报错了

 

pom.xml加入Maven编译插件，并配置JDK和编码：

    <build>
        <finalName>xxxfinalName>
        <plugins>
            <plugin>
                <groupId>org.apache.maven.pluginsgroupId>
                <artifactId>maven-compiler-pluginartifactId>
                <version>3.6.1version>
                <configuration>
                    <source>1.8source>
                    <target>1.8target>
                    <encoding>UTF8encoding>
                configuration>
            plugin>
        plugins>
    build>

保存后，项目右键Maven->Update ... 

 

由于自动构建的项目缺少src/test/resources目录，可以选择性地自行创建

Java Resource目录右键new source folder：

Project Name和项目名一致

Folder Name：src/test/resources

完成后

项目右键Properties->Java Build Path->Source

如果是最新版Eclipse，在src/test/java中选中Contains Test Source->Toggle

src/test/resources设置Output和src/test/java地Output路径一致

应用

 

设置Project Facets：可以省略，我设置只是为了提高效率

项目右键设置properties->搜索facets，设置Dynamic Web Module为3.1

发现设置失败，这是Eclipse的BUG，无论新旧版本

解决办法：进入项目路径.settins目录，打开目录中的XML文件：修改为下图所示

xml version="1.0" encoding="UTF-8"?>
<faceted-project>
  <fixed facet="wst.jsdt.web"/>
  <installed facet="jst.web" version="3.1"/>
  <installed facet="wst.jsdt.web" version="1.0"/>
  <installed facet="java" version="1.8"/>
faceted-project>

 web.xml也要修改为3.1版本：

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">

    <display-name>Archetype Created Web Applicationdisplay-name>
web-app>

 

测试：启动项目，如果正常跳到index.jsp说明准备工作顺利完成

 

接下来开始正式搭建SSM框架：

pom.xml：我选取了SSM框架和一些常用的包作为依赖

xml version="1.0" encoding="UTF-8"?>

新建两个source folder:

src/main/resources/spring：用于放Spring配置文件

src/main/resources/mapper：用于放MyBatis的映射文件

在src/main/resources下创建数据库连接配置文件：jdbc.properties：

jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/xxx?useUnicode=true&characterEncoding=utf8
jdbc.username=root
jdbc.password=xxx

 

在src/main/resources下创建MyBatis配置文件：mybatis-config.xml：

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>
    
    <settings>
        
        <setting name="useGeneratedKeys" value="true" />
        
        <setting name="useColumnLabel" value="true" />
        
        <setting name="mapUnderscoreToCamelCase" value="true" />
    settings>
configuration>

 

配置Spring：

在src/main/resources/spring下创建spring-dao.xml：

xml version="1.0" encoding="UTF-8"?>

        <property name="basePackage"

在src/main/resources/spring下创建spring-service.xml：

        <property name="dataSource" ref="dataSource" />
    bean>
    
    <tx:annotation-driven transaction-manager="transactionManager" />
beans>

 

在src/main/resources/spring下创建spring-web.xml：

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

    bean>
    
    <context:component-scan

web.xml中对Spring进行配置：顺便我也配置了验证码插件Kaptcha

到这里就配置完成了！

下面进行测试：

我写一个简单的实体类，并在数据库加入一条信息

package org.dreamtech.xiuxian.entity;

public class Person {

    private String userId;
    private Integer exp;
    private String stateId;
    private String username;
    private String password;

    public String getUserId() {
        return userId;
    }

    public void setUserId(String userId) {
        this.userId = userId;
    }

    public Integer getExp() {
        return exp;
    }

    public void setExp(Integer exp) {
        this.exp = exp;
    }

    public String getStateId() {
        return stateId;
    }

    public void setStateId(String stateId) {
        this.stateId = stateId;
    }

    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;
    }

    @Override
    public String toString() {
        return "Person [userId=" + userId + ", exp=" + exp + ", stateId=" + stateId + ", username=" + username
                + ", password=" + password + "]";
    }

}

 

Dao层测试：

package org.dreamtech.xiuxian.dao;

import org.apache.ibatis.annotations.Param;
import org.dreamtech.xiuxian.entity.Person;

public interface PersonDao {
    /**
     * 根据用户名和密码得到用户信息
     * 
     * @return 用户
     */
    Person getPersonByUsernameAndPassword(@Param("username") String username, @Param("password") String password);
}

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="org.dreamtech.xiuxian.dao.PersonDao">
    <select id="getPersonByUsernameAndPassword" resultType="Person">
        SELECT
        user_id,exp,state_id,username,password
        FROM
        tb_person
        WHERE
        username=#{username}
        AND
        password=#{password}
    select>
mapper>
    

package org.dreamtech.xiuxian.dao;

import org.dreamtech.xiuxian.entity.Person;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration({ "classpath:spring/spring-dao.xml" })
public class DaoTest {
    @Autowired
    private PersonDao personDao;

    @Test
    public void testPersonDao() {
        Person person = personDao.getPersonByUsernameAndPassword("test", "test");
        System.out.println(person.getUserId());
    }
}

Dao层测试成功！

 

Service层测试：

package org.dreamtech.xiuxian.service;

import org.dreamtech.xiuxian.entity.Person;

public interface PersonService {
    /**
     * 根据用户名和密码得到用户信息
     * 
     * @return 用户
     */
    Person getPersonByUsernameAndPassword(String username, String password);
}

package org.dreamtech.xiuxian.service.impl;

import org.dreamtech.xiuxian.dao.PersonDao;
import org.dreamtech.xiuxian.entity.Person;

}

Service层测试成功！

 

Controller层测试：

package org.dreamtech.xiuxian.web;

import java.util.HashMap;
import java.util.Map;

import javax.servlet.http.HttpServletRequest;

import org.dreamtech.xiuxian.entity.Person;
import org.dreamtech.xiuxian.service.PersonService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
@RequestMapping("/person")
public class PersonController {
    @Autowired
    private PersonService personService;

    @RequestMapping("login")
    private Map login(HttpServletRequest request) {
        String username = request.getParameter("username");
        String password = request.getParameter("password");
        Map modelMap = new HashMap();
        try {
            Person person = personService.getPersonByUsernameAndPassword(username, password);
            modelMap.put("person", person);
            modelMap.put("success", true);
        } catch (Exception e) {
            modelMap.put("success", false);
        }
        return modelMap;
    }
}

Controller层就不需要写测试类了，直接访问：

http://localhost:8080/xiuxian/person/login?username=test&password=test

 

所有测试完成！
