我在这里有一个春季启动应用程序:https : //github.com/christophstrobl/spring-data-solr-showcase/tree/4b3bbf945b182855003d5ba63a60990972a9de72
它可以与以下代码一起编译并正常工作: mvn spring-boot:run
但是,当我在Spring Tools Suite中单击“以Spring Boot应用程序运行”时,收到关于无法找到${solr.host}
application.properties文件中设置的错误。
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'productServiceImpl': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire method: public void org.springframework.data.solr.showcase.product.ProductServiceImpl.setProductRepository(org.springframework.data.solr.showcase.product.ProductRepository); nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'productRepository': Initialization of bean failed; nested exception is java.lang.IllegalArgumentException: Could not resolve placeholder 'solr.host' in string value "${solr.host}"
我的applications.properties文件如下所示:
# SPRING MVC
spring.view.suffix=.jsp
spring.view.prefix=/WEB-INF/views/
# SOLR
solr.host=http://192.168.56.11:8983/solr
相关类如下所示(使用$ solr.host变量的唯一位置)。另外,如果我直接寻址SOLR服务器的IP(如注释的代码所示),则应用程序启动正常。

我包括该“ ProductRepository”(错误中提到的那个),尽管那里没有太多活动...

我有一个看起来像“标准”文件结构的文件……src / main / java中的代码,依此类推。application.properties文件位于src / main / resources中。
任何建议表示感谢。
(快速补充:这是将Tomcat作为嵌入式服务器运行)
这很晦涩-其他答案对帮助我指出正确的方向很有帮助。
在尝试了建议的解决方案之后,我进行了更深入的研究,并在项目属性-> Java构建路径-> Source(tab)->构建路径上的Source文件夹中找到了这一点:[排除部分]
**/application.properties
删除排除项解决了该问题,并且在启动期间从application.properties文件中获取了值。
可能值得注意的是,从命令行(在带有.project文件的目录中)运行此命令可以绕过排除问题并可以正常工作。
mvn spring-boot:run
