spring-boot 多模块的搭建
(1)项目的结构：搭建spring-boot多模块时，需要有一个父模块作为所有子模块的统一依赖，父模块有时只是一个文件夹，文件夹中放着父类的pom.xml文件，子模块的文件夹。比如我将建立3个子模块，我的目录结构是这样的：
在dataCollection文件夹下：有collection1,collection2,collection3和pom.xml.其中pom.xml是父类的pom.xml.
(2)创建项目：以eclipse为例，打开file->new->maven project->next->next->maven-archetype-quickstart->next->填写groupId和artifactId(项目名,这里dataCollection）->finish;
删除除pom.xml外的其他文件，在pom.xml中配置maven的相关依赖：
4.0.0
cdmvs-dataColl
dataCollection
0.0.1-SNAPSHOT
pom
dataCollection
http://maven.apache.org
org.springframework.boot
spring-boot-starter-parent
1.3.0.RELEASE
UTF-8
4.2.3.RELEASE
1.3.0.RELEASE
collection1
collection2
collection3
org.apache.maven.plugins
maven-compiler-plugin
3.6.0
1.8
1.8
接下来创建子项目collection1,collection2,collection3:
以colleciton1为例，collection2和collection3同理：file->new->maven project->next->next->maven-archetype-quickstart->next->填写groupId和artifactId(项目名,这里collection1）->finish;
colleciton1,2,3的pom.xml如下：
4.0.0
cdmvs-dataColl
collection2
0.0.1-SNAPSHOT
collection2
http://maven.apache.org
cdmvs-dataColl
dataCollection
0.0.1-SNAPSHOT
UTF-8
比如本文我是collection1作为spring boot启动点，collection2做为controller 层，collection3暂时没想到,那我collection1则应该依赖springboot的相关配置依赖，ok,引入maven如下：
4.0.0
cdmvs-dataColl
collection1
0.0.1-SNAPSHOT
jar
collection1
http://maven.apache.org
cdmvs-dataColl
dataCollection
0.0.1-SNAPSHOT
UTF-8
org.springframework.boot
spring-boot-starter-web
org.springframework.boot
spring-boot-devtools
true
org.springframework.boot
spring-boot-dependencies
1.3.5.RELEASE
pom
import
4.0.0
cdmvs-dataColl
collection2
0.0.1-SNAPSHOT
collection2
http://maven.apache.org
cdmvs-dataColl
dataCollection
0.0.1-SNAPSHOT
UTF-8
org.springframework
spring-webmvc
${spring.version}
package cdmvs_dataColl_collection3;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
/**
* Hello world!
*
*/
@Configuration
@SpringBootApplication
@ComponentScan(basePackages = "cdmvs_dataColl_collection2")//这里是什么鬼？
public class App
{
private static Logger logger= LoggerFactory.getLogger(App.class);
public static void main( String[] args )
{
SpringApplication.run(App.class, args);
}
}
在app.java 文件中有一个这样的注解：@ComponentScan(basePackages = "cdmvs_dataColl_collection2")
package cdmvs_dataColl_collection2;
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;
/**
* Hello world!
*
*/
@Controller
public class AppController
{
@RequestMapping(value="/hello", method=RequestMethod.GET)
@ResponseBody
public String hello(){
return "hello world";
}
}
然后在collection1的pom.xml中将collection1引入：
cdmvs-dataColl
collection1
${project.version}
