Question

我使用Spring Initializr创建了spring boot应用程序，它生成在pom.xml下面

.....
<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.0.1.RELEASE</version>
    <relativePath/> <!-- lookup parent from repository -->
</parent>

<properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
    <java.version>1.8</java.version>
</properties>

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

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

        <groupId>com.h2database</groupId>
        <artifactId>h2</artifactId>

    <dependency>
        <groupId>org.springframework.security</groupId>
        <artifactId>spring-security-test</artifactId>
        <scope>test</scope>
    </dependency>        
</dependencies>

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

但是当我试图让它运行时低于错误。我不确定为什么它在spring.factories文件中失败。

我的应用程序很简单，没有任何配置，我不确定我需要添加到spring.factories文件中。

Answer 1

当使用spring初始化程序创建相同项目时，它适用于我。

您没有指定尝试启动项目的方式，请尝试以下操作：

mvn clean install
mvn spring-boot:run

来自命令行。

Answer 2

SpringFactoriesLoader尝试加载spring.factories但无法从META-INF/spring.factories找到该文件。由于spring.factories用于Auto-configured Beans，您需要检查是否使用了@EnableAutoConfiguration，@ConditionalOnClass或@ConditionalOnMissingBean种注释。确保您知道正在使用的注释。

解决方法是在spring.factories文件夹下放置一个空白文件META-INF。

无法从位置加载工厂[META-INF / spring.factories]
