Maven自身提供了许多Archetype来方便用户创建Project,但是每个团队都可能会有一些常用的文件或配置,为了避免在创建project时重复的拷贝和修改,我们通过自定义Archetype来规范显得还蛮有必要,下面简单介绍下使用maven-archetype-archetype来构建自己的Archetype的过程。
模板
mvn archetype:generate \
-DarchetypeGroupId=<archetype-groupId> \
-DarchetypeArtifactId=<archetype-artifactId> \
-DarchetypeVersion=<archetype-version> \
-DgroupId=<my.groupid> \
-DartifactId=<my-artifactId>
例如:
mvn archetype:generate \
-DgroupId=com.ultrapower.maven.archetypes \
-DartifactId=springboot-maven-archetype \
-DarchetypeArtifactId=maven-archetype-archetype \
-DinteractiveMode=false \
-X
1) springboot-maven-archetype下的pom.xml和一般的maven项目一样用于定义archetype项目的坐标等信息
2) springboot-maven-archetype/src/main/resources/archetype-resources下的所有内容定义了待生成项目的所有文件(原型文件)
3) springboot-maven-archetype/ src/main/resources/META-INF/maven/archetype.xml中定义骨架的描述符(元数据),这个文件列出了包含在archetype中的所有文件并将这些文件分类。
注:springboot-maven-archetype/pom.xml如下

例如:

package ${package};
import org.springframework.boot.Banner;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration;

import org.springframework.boot.autoconfigure.orm.jpa.HibernateJpaAutoConfiguration;
import org.springframework.boot.web.servlet.FilterRegistrationBean;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
@SpringBootApplication(exclude = { DataSourceAutoConfiguration.class, HibernateJpaAutoConfiguration.class,

@ServletComponentScan
@ComponentScan(basePackages = { "${package}" })
public class Application {
public static void main(String[] args) {
SpringApplication app = new SpringApplication(Application.class);
app.setBannerMode(Banner.Mode.OFF);
app.run(args);
}
}
如CorsConfig.java
package ${package}.config.beanconfig;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.cors.CorsConfiguration;
import org.springframework.web.cors.UrlBasedCorsConfigurationSource;
import org.springframework.web.filter.CorsFilter;
@Configuration
public class CorsConfig {
private CorsConfiguration buildConfig() {
CorsConfiguration corsConfiguration = new CorsConfiguration();
// 1 设置访问源地址
corsConfiguration.addAllowedOrigin("*");
// 2 设置访问源请求头
corsConfiguration.addAllowedHeader("*");
// 3 设置访问源请求方法
corsConfiguration.addAllowedMethod("*");
return corsConfiguration;
}
@Bean
public CorsFilter corsFilter() {
UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
// 4 对接口配置跨域设置
source.registerCorsConfiguration("/**", buildConfig());
return new CorsFilter(source);
}
}
如:
<archetype xmlns="http://maven.apache.org/plugins/maven-archetype-plugin/archetype/1.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/plugins/maven-archetype-plugin/archetype/1.0.0 http://maven.apache.org/xsd/archetype-1.0.0.xsd">

</resources>
<testSources>
<source>src/test/java/AppTest.java</source>
</testSources>
</archetype>
上面是将每个文件都列出来了,还可以使用通配符的方式来简化配置,例如:
<archetype xmlns="http://maven.apache.org/plugins/maven-archetype-plugin/archetype/1.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/plugins/maven-archetype-plugin/archetype/1.0.0 http://maven.apache.org/xsd/archetype-1.0.0.xsd">
<id>springboot-maven-archetype</id>
<sources>
<source encoding="UTF-8">src/main/java/**/*.*</source>
</sources>
<resources>
<resource encoding="UTF-8">**/*.*</resource>
</resources>
<testSources>
<source>src/test/java/AppTest.java</source>
</testSources>
</archetype>
mvn install
mvn archetype:generate -DarchetypeGroupId=com.ultrapower.maven.archetypes -DarchetypeArtifactId=springboot-maven-archetype -DarchetypeVersion=1.0-SNAPSHOT -DgroupId=com.ultrapower.ioss -DartifactId=springboot-archetype-test -X
注意: 我们可以将archetype.xml换成“archetype-metadata.xml”,以下的内容可以达到同样的效果,但还是推荐archetype.xml
<?xml version="1.0" encoding="UTF-8"?>
