springboot多模塊項目（包含頁面）創建和打包發佈-2

二、規定依賴關係

1、parent項目pom依賴：

</project>

可以看到，pom文件中使用的是

 <dependencies>
 </dependencies>

如此使用，父項目所依賴的包，子項目都能夠使用，而且子項目可以重複添加依賴並使用不同版本，如果沒有必要，對於統一使用的或者版本確定的都放在這裏面就可以；
如果不想讓子項目使用父項目的pom依賴，可以使用

<dependencyManagement></dependencyManagement>

關於dependencyManagement的作用，可自行查找補習，這裏只做引導；

2、common模塊：

根據項目要求，我們規定，common模塊是最基礎的模塊，不包含頁面，只是一些公共的工具類或者加密解密之類的包依賴使用；

3、baseService

此模塊是系統基礎模塊，主要負責權限控制，菜單用戶管理之類的，也就是基礎的系統權限管理；此模塊依賴common，並且有自身的頁面；

關於自定義啓動類如下：

import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;
import org.springframework.context.ConfigurableApplicationContext;

@SpringBootApplication(scanBasePackages="com.tzwy.mcsp")
@MapperScan(basePackages = "com.tzwy.mcsp.base.mapper")
public class MainApplication extends SpringBootServletInitializer {

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
        return builder.sources(MainApplication.class);
    }

    public static void main(String[] args) throws Exception {
        ConfigurableApplicationContext run = SpringApplication.run(MainApplication.class, args);
    }
}

在pom文件中添加對common模塊的依賴，頁面模板引擎使用freemarker：

  <!--依賴common模塊-->
        <dependency>
            <groupId>com.tzwy.mcsp</groupId>
            <artifactId>common</artifactId>
            <version>${project.parent.version}</version>
        </dependency>
        <!--freemarker-->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-freemarker</artifactId>
        </dependency>

4、esmService

此模塊是建立在common和baseService之上的；要使用common中工具，並且要被baseService的權限所控制；同樣，此模塊帶有自己的頁面：

可以看到該模塊也有自己的啓動類，代碼如下：

import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;
import org.springframework.context.ConfigurableApplicationContext;

@SpringBootApplication(scanBasePackages="com.tzwy.mcsp")
@MapperScan(basePackages = "com.tzwy.mcsp.base.mapper")
public class EsmMainApplication extends SpringBootServletInitializer {

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
        return builder.sources(EsmMainApplication.class);
    }

    public static void main(String[] args) throws Exception {
        ConfigurableApplicationContext run = SpringApplication.run(EsmMainApplication.class, args);
    }
}

pom文件中添加對baseService模塊的依賴（baseService中已經依賴common，在這裏不必重複依賴）：

 <dependencies>
        <!--依賴baseService模塊-->
        <dependency>
            <groupId>com.tzwy.mcsp</groupId>
            <artifactId>baseService</artifactId>
            <version>${project.parent.version}</version>
        </dependency>

    </dependencies>

如此，各模塊基本依賴關係完成；
