spring boot到Tomcat部署數據源問題

Question

我正在使用Spring Boot，Neo4j和MongoDB構建應用程序。 我使用@Configuration批注從application.properties加載數據庫屬性，如下所示：

@Bean(name = "neoDriver")
@Profile("local")
public Driver getNeoDriver() {

    return GraphDatabase.driver(
      env.getProperty("datasource.neo4j.uri"),
      AuthTokens.basic(env.getProperty("datasource.neo4j.username"), env.getProperty("datasource.neo4j.password")),
      Config.build().toConfig());
}

autowire代碼是

@Autowired
@Qualifier("neoDriver")
private Driver neoDriver;

當我從IntelliJ運行應用程序時，它運行良好; 但是當我嘗試在Tomcat 8.5上部署war文件時，它會出錯。

Field neoDriver in com......repository.PositionRepositoryImpl required a bean of type 'org.neo4j.driver.v1.Driver' that could not be found.

Caused by:
org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'Controller': Unsatisfied dependency expressed through field 'positionService'; nested exception is
org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'Service': Unsatisfied dependency expressed through field 'positionRepository'; nested exception is
org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'RepositoryImpl': Unsatisfied dependency expressed through field 'neoDriver'; nested exception is
org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'org.neo4j.driver.v1.Driver' available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations:
{@org.springframework.beans.factory.annotation.Autowired(required=true), @org.springframework.beans.factory.annotation.Qualifier(value=neoDriver)}

請讓我知道在Tomcat上部署它時我做錯了什么。

我敢打賭你沒有在你的Tomcat部署spring.profiles.active設置為local 。 因為您的bean標有@Profile注釋，所以只有在該配置文件處於活動狀態時才會創建它。
