项目环境: JDK7+Maven3.04
项目架构：SpringMVC
- 方法一：API访问Maven生成的MANIFEST.MF
1. 在pom.xml中添加jar包支持
<dependency>
<groupId>com.jcabi</groupId>
<artifactId>jcabi-manifests</artifactId>
<version>1.1</version>
</dependency>
2. pom.xml配置
配置archive添加
built-at: 编译时间
env: 环境
project-version: 代码分支号
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-war-plugin</artifactId>
<version>2.4</version>
<executions>
<execution>
<id>artifact-package</id>
<phase>package</phase>
<goals>
<goal>war</goal>
</goals>
<configuration>
<archiveClasses>true</archiveClasses>
<warSourceExcludes>WEB-INF/lib/servlet-*</warSourceExcludes>
<archive>
<manifestEntries>
<built-at>${maven.build.timestamp}</built-at>
<env>${env}</env>
<project-version>${project.version}</project-version>
</manifestEntries>
</archive>
</configuration>
</execution>
<execution>
<id>local-package</id>
<phase>package</phase>
<goals>
<goal>exploded</goal>
</goals>
<configuration>
<primaryArtifact>false</primaryArtifact>
<webappDirectory>${project.build.directory}/hiv-local</webappDirectory>
<archiveClasses>true</archiveClasses>
<warSourceExcludes>WEB-INF/lib/servlet-*</warSourceExcludes>
<archive>
<manifestEntries>
<built-at>${maven.build.timestamp}</built-at>
<env>${env}</env>
<project-version>${project.version}</project-version>
</manifestEntries>
</archive>
</configuration>
</execution>
</executions>
</plugin>
3. 编译后结果如下
META-INF/MANIFEST.MF
Manifest-Version: 1.0
Built-By: dell
Build-Jdk: 1.7.0_75
project-version: develop-SNAPSHOT
Created-By: Apache Maven 3.0.4
built-at: 2015-07-02 13:35:38
env: qa
Archiver-Version: Plexus Archiver
4. 配置API访问编译结果并输出
@Controller
public class VersionController {
@Resource
private ServletContext context; @ResponseBody
@RequestMapping(value = "/version", method = RequestMethod.GET)
@ApiOperation(value = "查看编译版本", response = Map.class, httpMethod = "GET", notes = "查看编译版本")
public Map<String, String> version(HttpServletRequest request) throws IOException {
Map<String, String> map = new HashMap<String, String>();
MfMap mfMap = Manifests.DEFAULT.append(new ServletMfs(context));
map.put("project-version", mfMap.get("project-version"));
map.put("env", mfMap.get("env"));
map.put("built-at", mfMap.get("built-at"));
return map;
}
}
5. 打成war包启动结果如下：
{"project-version":"develop-SNAPSHOT","built-at":"2015-07-02 13:35:38","env":"qa"}

- 方法二：使用maven生成变量
1. 在pom.xml文件中配置
<properties>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
<maven.build.timestamp.format>yyyy-MM-dd HH:mm:ss</maven.build.timestamp.format>
<timestamp>${maven.build.timestamp}</timestamp>
</properties>
2. 在properties文件中配置
project.version=${project.version}
project.env=${env}
project.built.time=${timestamp}
3. 配置API访问编译结果并输出
@Controller
public class VersionController {
@Value("${project.version}")
private String version;
@Value("${project.env}")
private String env;
@Value("${project.built.time}")
private String builtAt; @ResponseBody
@RequestMapping(value = "version", method = GET)
@ApiOperation(value = "查看版本信息")
public Map<String, String> version() {
Map<String, String> map = new HashMap<String, String>();
map.put("project-version", version);
map.put("env", env);
map.put("built-at", builtAt);
return map;
} }
