更新時(shí)間：2024年10月25日 11:59:44 作者：GreaterBuilder
在軟件開(kāi)發(fā)中,利用Spring?Boot進(jìn)行分模塊項(xiàng)目搭建能夠提高代碼的模塊化和復(fù)用性,本文主要介紹了Springboot分模塊項(xiàng)目搭建的實(shí)現(xiàn),感興趣的可以了解一下
一、創(chuàng)建聚合父工程
(1) eclipse -> File -> new -> Other… -> Maven -> Maven Project
(2) configure project
(3) pom.xml配置

二、創(chuàng)建springboot-web
(1) 右鍵點(diǎn)擊父工程 -> new -> Other… -> Maven -> Maven Module
(2) pom.xml
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <artifactId>springboot-web</artifactId> <packaging>jar</packaging> <name>springboot-web</name> <parent> <groupId>com.button</groupId> <artifactId>springboot-parent</artifactId> <version>0.0.1-SNAPSHOT</version> </parent> <!-- Web模塊相關(guān)依賴 --> <dependencies> <dependency> <groupId>com.button</groupId> <artifactId>springboot-service</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-devtools</artifactId> <optional>true</optional> <scope>true</scope> </dependency> </dependencies> <!--只需在啟動(dòng)類(lèi)所在模塊的POM文件：指定打包插件 --> <build> <plugins> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-compiler-plugin</artifactId> <configuration> <source>1.8</source> <target>1.8</target> </configuration> </plugin> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> <configuration> <jvmArguments>-Dfile.encoding=UTF-8</jvmArguments> <fork>true</fork><!-- 沒(méi)有該配置，devtools 不生效 --> </configuration> </plugin> </plugins> </build> </project>
解釋：
pom文件中的如下配置：
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-devtools</artifactId>
<optional>true</optional>
<scope>true</scope>
</dependency>
<build>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
<configuration>
<!-- 沒(méi)有該配置，devtools 不生效 -->
<fork>true</fork>
</configuration>
</plugin>
</plugins>
</build>
如上的兩項(xiàng)配置，添加之后會(huì)打開(kāi)springboot的熱部署，這樣每次修改文件之后，不用手動(dòng)重新啟動(dòng)項(xiàng)目。配置熱部署可以讓項(xiàng)目自動(dòng)加載變化的文件，省去的手動(dòng)操作。(項(xiàng)目搭建好之后，啟動(dòng)項(xiàng)目，隨便創(chuàng)建/修改一個(gè)文件并保存，會(huì)發(fā)現(xiàn)控制臺(tái)打印 springboot 重新加載文件的log。)
三、創(chuàng)建springboot-service
參照如上創(chuàng)建方式
pom.xml
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <artifactId>springboot-service</artifactId> <packaging>jar</packaging> <name>springboot-service</name> <parent> <groupId>com.button</groupId> <artifactId>springboot-parent</artifactId> <version>0.0.1-SNAPSHOT</version> </parent> <dependencies> <dependency> <groupId>com.button</groupId> <artifactId>springboot-dao</artifactId> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context-support</artifactId> </dependency> </dependencies> </project>

2、springboot-entity

import java.io.Serializable;
public class UserModel implements Serializable{
private static final long serialVersionUID = 1L;
private Integer id;
private String name;
private Integer age;
public Integer getId() {
return id;

public void setId(Integer id) {
this.id = id;

public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public Integer getAge() {
return age;
}
public void setAge(Integer age) {
this.age = age;
}
@Override
public String toString() {
return "UserModel [id=" + id + ", name=" + name + ", age=" + age + "]";
}
}
3、springboot-service
①UserService.java
package com.button.project.service;
import java.util.List;
import com.button.project.pojo.UserModel;
public interface UserService {
List<UserModel> getUser();
}
②UserServiceImpl.java
package com.button.project.service.impl;
import java.util.List;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import com.button.project.dao.UserMapper;

import com.button.project.service.UserService;
@Service
public class UserServiceImpl implements UserService {
@Autowired
private UserMapper userMapper;
@Override
public List<UserModel> getUser() {
return userMapper.getUser();
}
}
4、springboot-web
①UserController.java
package com.button.project.controller;
import java.util.List;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import com.button.project.pojo.UserModel;
@RequestMapping(value = "/user", produces = "application/json;charset=UTF-8")
public interface UserController {
@RequestMapping(value = "/getUser", method={RequestMethod.POST, RequestMethod.GET})
List<UserModel> getUser();
}
②UserControllerImpl.java
package com.button.project.controller.impl;
import java.util.List;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RestController;
import com.button.project.controller.UserController;
import com.button.project.pojo.UserModel;
import com.button.project.service.UserService;
@RestController
public class UserControllerImpl implements UserController {
@Autowired
private UserService userService;
@Override
public List<UserModel> getUser() {
return userService.getUser();
}
}
③SpringBootApplicationService
package com.button.project;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.web.servlet.ServletComponentScan;
import org.springframework.cache.annotation.EnableCaching;
import org.springframework.context.annotation.ImportResource;
import org.springframework.transaction.annotation.EnableTransactionManagement;
@ImportResource("classpath:config/application-mybatis.xml")
@ServletComponentScan
@EnableCaching
@EnableTransactionManagement
@SpringBootApplication
public class SpringBootApplicationService {
//項(xiàng)目啟動(dòng)入口
public static void main(String[] args) {
SpringApplication.run(SpringBootApplicationService.class, args);
}
}④InitConstantListener.java
package com.button.project.init;
import javax.servlet.ServletContextEvent;
import javax.servlet.ServletContextListener;
import javax.servlet.annotation.WebListener;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
@WebListener
public class InitConstantListener implements ServletContextListener {
private static final Logger logger = LoggerFactory.getLogger(InitConstantListener.class);
@Override
public void contextInitialized(ServletContextEvent sce) {
logger.info("初始化數(shù)據(jù).");
}
@Override
public void contextDestroyed(ServletContextEvent sce) {
logger.info("銷(xiāo)毀數(shù)據(jù).");
}
}⑤application.yml

⑥logback.xml
<?xml version="1.0" encoding="UTF-8"?>
<configuration scan="true" scanPeriod="30 seconds">
<property name="LOG_HOME" value="/com/button/" />
<appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">

</appender>
<appender name="FILE"

<root level="DEBUG">
<appender-ref ref="STDOUT" />
<appender-ref ref="FILE" />
</root>
</configuration>
七、完整項(xiàng)目結(jié)構(gòu)如下：
注：一個(gè)項(xiàng)目從開(kāi)發(fā)，測(cè)試再到生產(chǎn)，可能會(huì)使用到不同的配置信息，每次去修改application.yml文件中的信息就顯得特別麻煩，可以使用如下方式解決。
比如項(xiàng)目運(yùn)行環(huán)境開(kāi)發(fā)(dev)，測(cè)試(test)，生產(chǎn)(prod)，我們可以在src/main/resources文件夾下創(chuàng)建如下四個(gè)文件：
application-dev.yml
server:
servlet:
context-path: /button-dev
port: 8080
uri-encoding: utf-8
application-test.yml
server:
servlet:
context-path: /button-test
port: 8081
uri-encoding: utf-8
application-prod.yml
server:
servlet:
context-path: /button-prod
port: 8082
uri-encoding: utf-8
這三個(gè)文件配置好項(xiàng)目不同環(huán)境的配置信息
application.yml文件配置如下：
spring:
profiles:
active: dev
解釋：active后可以配置dev、test、prod，不同的配置會(huì)去加載不同的配置信息，這樣就不用來(lái)回修改配置信息了。
