SpringBoot中未标识java自定义依赖项

Question

我有两个spring boot项目

1. 迎宾图书馆
2. 迎宾弹簧靴自动配置

我已经为greeter库创建了jar文件，并将其安装在本地m2（maven）存储库中。 现在，我在greeter spring boot autoconfigure中将该jar用作maven依赖项。但它是在陈述 在Greeter上找不到类。爪哇

波姆。用于greeter库的xml

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.4.1</version>
    <relativePath/> <!-- lookup parent from repository -->
</parent>


<artifactId>greeter-library</artifactId>
<groupId>com.xyz.greeter</groupId>
<version>0.0.1-SNAPSHOT</version>
<name>greeter-library</name>
<dependencies>
 <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>
</dependencies>

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

现在是波姆。greeter spring boot自动配置的xml如下

<artifactId>greeter-spring-boot-autoconfigure</artifactId>
<name>greeter-spring-boot-autoconfigure</name>
<groupId>com.xyz</groupId>


<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.4.1</version>
    <relativePath /> <!-- lookup parent from repository -->
</parent>

<dependencies>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot</artifactId>
    </dependency>

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-autoconfigure</artifactId>
    </dependency>

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-configuration-processor</artifactId>
        <optional>true</optional>
    </dependency>

    <dependency>
        <artifactId>greeter-library</artifactId>
        <groupId>com.xyz.greeter</groupId>
        <version>0.0.1-SNAPSHOT</version>
    </dependency>
</dependencies>
<build>
    <plugins>
        <plugin>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
        </plugin>
    </plugins>
</build>

但在maven为greeter spring boot autoconfigure构建时，它表明greeter。找不到属于greeter library项目的java

有人能解决这个问题吗

Answer 1

一些需要探索的想法

1. spring boot不需要打包第一个jar“greeter library”，它可以是一个普通的jar文件
2. 创建一个弹簧。工厂文件位于src/resources/META-INF路径下。从这个JAR中公开“greeter spring boot autoconfigure”可以使用的java类
