是否可以创建没有数据源的spring-boot应用程序?就我而言,我只需要一个简单的REST应用程序,但似乎在启动时就尝试自动初始化数据源
我的pom.xml是
<?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>a.b.c.d.test</groupId> <artifactId>rest-customer-builder</artifactId> <version>0.0.1-SNAPSHOT</version> <packaging>war</packaging> <name>rest-customer-builder</name> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>1.2.5.RELEASE</version> <!--<relativePath/> lookup parent from repository --> </parent> <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> <java.version>1.7</java.version> </properties> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-tomcat</artifactId> <scope>provided</scope> </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> </project>
我的application.properties是
server.contextPath=/rest-customer-builder server.port=9090
当我跑步
mvn clean install spring-boot:run
我看到这个错误

可以在没有数据源的情况下运行spring boot应用程序。您必须禁用数据源的自动配置,并且可能也适用于JPA:
@EnableAutoConfiguration(exclude={DataSourceAutoConfiguration.class,HibernateJpaAutoConfiguration.class})
您发布的异常是其他内容,如注释中所写,您的类路径中有某些内容引用了apache geronimo缺少的类。因此,您必须摆脱引用geronimo的代码/ jar或将geronimo添加到您的依赖项中。
