Question

是否可以创建一个没有数据源的spring-boot应用程序？在我的情况下，我只需要一个简单的REST应用程序，但似乎在启动时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"

</project>

我的application.properties是

server.contextPath=/rest-customer-builder
server.port=9090

当我跑步时

mvn clean install spring-boot:run

我看到了这个错误

Answer 1

It is possible to run a spring boot application without datasource. You must disable the auto configuration for the datasource and may be for JPA also :

@EnableAutoConfiguration(exclude={DataSourceAutoConfiguration.class,HibernateJpaAutoConfiguration.class})

The exception you posted is something else, as written in the comments, you have something in the classpath that references the missing class of apache geronimo. So you must get rid of the code/jar that references geronimo or add geronimo to your dependencies.

Answer 2

解决这一问题的更好方法是从POM / Gradle配置文件中删除依赖项，Spring Boot不会尝试自动配置DataSource。

Answer 3

@Stefan +1 如果您正在使用YAML文件进行配置，那么它就是这样的

spring:
  profiles: dev
  autoconfigure:
    exclude:
    - org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration
    - org.springframework.boot.autoconfigure.orm.jpa.HibernateJpaAutoConfiguration

它对我来说非常好。

Answer 4

我遇到了这个问题，一旦删除了以下依赖项，它便开始工作。

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

Answer 5

在application.properties文件中提供spring.datasource.url。它对我有用。例： spring.datasource.url = JDBC：MySQL的：//本地主机/ TEST_DB

没有数据源的spring-boot应用程序
