新调度平台-2-基础环境搭建

 
  一、项目建立 
 

 
  1、使用eclipse建立maven项目“YYSchedule-parent” 
 

 
  2、建立项目YYSchedule-common 
 

 
  2、建立项目YYSchedule-storemanager 
 

 
  3、建立项目YYSchedule-taskmanager 
 

 
  4、建立项目YYSchedule-nodemanager 
 

二、在“YYSchedule-parent”中添加依赖（详见pom.xml），注意要将打包方式设置成pom

在“YYSchedule-storemanager”中添加依赖，父工程为parent

在“YYSchedule-taskmanager”中添加依赖，父工程为parent

在“YYSchedule-nodemanager”中添加依赖，父工程为parent

 
  三、mybatis自动生成mapper（也就是dao层） 
 

 
  1、使用自动生成工具生成mapper文件和pojo文件。 
 

 
  参考博文：http://blog.csdn.net/zhshulin/article/details/23912615 
 

 
  2、mapper文件夹的文件一起放在storemanager下，pojo文件夹放在common文件夹下 
 

最最最重要的一点！！

在storemanager的pom文件中写入如下：

        <resources>
            <resource>
                <directory>src/main/java</directory>
                <includes>
                    <include>**/*.xml</include>
                </includes>
            </resource>
            <resource>
                <directory>src/main/resources</directory>
                <includes>
                    <include>**.*</include>
                </includes>
            </resource>
        </resources>

四、在taskmanager项目中配置spring等配置文件

src/main/resources文件夹中创建mybatis文件夹，properties文件夹以及spring文件夹（记得把resources文件夹add to build path）

并在里面各自创建配置文件，如下图所示：

SqlMapConfig.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>
	<plugins>
	    <!-- com.github.pagehelper为PageHelper类所在包名 -->
	    <plugin interceptor="com.github.pagehelper.PageHelper">
	        <!-- 设置数据库类型 Oracle,Mysql,MariaDB,SQLite,Hsqldb,PostgreSQL六种数据库-->        
	        <property name="dialect" value="mysql"/>
	    </plugin>
	</plugins>
</configuration>

db.properties:

jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://192.168.25.134:3306/taotao?characterEncoding=utf-8
jdbc.username=root
jdbc.password=root

applicationContext-dao.xml:

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

		<!-- 指定要扫描的包 -->

	</bean>
</beans>

applicationContext-service.xml:（其他地方不变，所以）

		<aop:advisor advice-ref="txAdvice"

	</aop:config>
</beans>

五、在storemanager中创建service层

1、将common模块引入到storemanager模块中，方法： 
   （File-project structure-选择storemanager-dependencies-“+”号-module dependency-选择common点击ok） 
  

 
  2、创建package，com.binto.schedule.storemanager.service以及xxxx.service.impl 
 

 
  3、编写UserBasicService类以及UserBasicServiceImpl 
 

 
  UserBasicServiceImpl类：（注意一定要有@Service注解！）

@Service
public class UserBasicServiceImpl implements UserBasicService {
    @Resource
    UserBasicMapper userBasicMapper;

    @Override
    public UserBasic getUserBasicMapperById(Integer userId) {
        UserBasicExample userBasicExample = new UserBasicExample();
        UserBasicExample.Criteria criteria = userBasicExample.createCriteria();
        criteria.andUserIdEqualTo(1);

        List<UserBasic> userBasicList = userBasicMapper.selectByExample(userBasicExample);
        UserBasic userBasic = null;
        if(userBasicList != null && userBasicList.size() > 0 )
        {
            userBasic = userBasicList.get(0);
        }
        return userBasic;
    }
}

4、在taskmanager中编写测试类，用于测试

public class UserBasicServiceTest
{
	private ApplicationContext applicationContext;

	@Before
	public void init() {
		//创建一个spring容器
		applicationContext = new ClassPathXmlApplicationContext("classpath:spring/applicationContext-*.xml");
	}
	
    @Test
    public void testGetUserBasicMapperById()
    {
        UserBasicService userBasicService = applicationContext.getBean(UserBasicService.class);
    	
        int userId = 1;

        UserBasic userBasic= userBasicService.getUserBasicMapperById(userId);

        System.out.println(userBasic.getUsername());
    }
}

测试成功！
