spring boot 属性启动器无法使用 [英] spring boot properties launcher unable to use

问题描述

我正在尝试使用 Spring Boot 属性启动器

i am trying to use the spring boot properties launcher

<plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-jar-plugin</artifactId>
            <configuration>
                <archive>
                    <manifest>
                        <mainClass>org.springframework.boot.loader.PropertiesLauncher</mainClass>
                    </manifest>
                    <manifestEntries>
                        <Start-Class>com.att.hadoop.loader.run.Application</Start-Class>
                    </manifestEntries>
                </archive>
            </configuration>
        </plugin>

        <plugin>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
        </plugin>
    </plugins>

当我查看清单文件时，它看起来像这样

when i look at manifest file it looks like this

$ unzip -q -c hdfsloader-0.0.1-SNAPSHOT.jar META-INF/MANIFEST.MF
Manifest-Version: 1.0
Built-By: aq728y
Build-Jdk: 1.7.0_25
Start-Class: org.springframework.boot.loader.PropertiesLauncher
Created-By: Apache Maven 3.1.0
Spring-Boot-Version: 1.0.0.RC1
Main-Class: org.springframework.boot.loader.JarLauncher
Archiver-Version: Plexus Archiver

关于为什么我的 mainclass 和 startclass 是错误的任何想法

any ideas on why my mainclass and startclass are wrong

我想设置为

主类:org.springframework.boot.loader.PropertiesLauncher

Main-Class: org.springframework.boot.loader.PropertiesLauncher

起始类:com.att.hadoop.loader.run.Application

Start-Class: com.att.hadoop.loader.run.Application

推荐答案

spring-boot-maven-plugin 重写你的清单，特别是它管理 Main-Class 和 Start-Class 条目，所以你必须在那里配置那些(不是在 jar 插件中).manifest中的Main-Class实际上是由boot插件的layout属性控制的，例如

The spring-boot-maven-plugin rewrites your manifest, and in particular it manages the Main-Class and Start-Class entries, so you have to configure those there (not in the jar plugin). The Main-Class in the manifest is actually controlled by the layout property of the boot plugin, e.g.

<plugin>
  <groupId>org.springframework.boot</groupId>
  <artifactId>spring-boot-maven-plugin</artifactId>
  <version>1.0.0.RC1</version>
  <configuration>
    <mainClass>${start-class}</mainClass>
    <layout>ZIP</layout>
  </configuration>
  <executions>
    <execution>
      <goals>
        <goal>repackage</goal>
      </goals>
    </execution>
  </executions>
</plugin>

布局属性默认为基于存档类型(JAR 或 WAR)的猜测.对于 PropertiesLauncher，布局为ZIP".

The layout property defaults to a guess based on the archive type (JAR or WAR). For the PropertiesLauncher the layout is "ZIP".
