我正在嘗試創建一個使用JNDI連接到數據庫的測試spring啓動項目。這裏是我的application.properties
:Spring Boot JNDI應用程序設置
spring.datasource.name=jdbc/test
spring.datasource.driver-class-name=com.microsoft.sqlserver.jdbc.SQLServerDriver
spring.datasource.jndi-name=java:jdbc/test
spring.datasource.url=...
spring.datasource.username=...
spring.datasource.password=...
spring.datasource.type=javax.sql.DataSource
spring.datasource.separator=;
這裏是我的配置文件:
@Configuration
@EnableConfigurationProperties
public class AppConfig {
@Bean
public TomcatEmbeddedServletContainerFactory tomcatFactory() {
return new TomcatEmbeddedServletContainerFactory() {
@Override
protected TomcatEmbeddedServletContainer getTomcatEmbeddedServletContainer(Tomcat tomcat) {
tomcat.enableNaming();
return super.getTomcatEmbeddedServletContainer(tomcat);
}
};
}
@Bean
@ConfigurationProperties(prefix = "spring.datasource")
public DataSource dataSource() {
JndiDataSourceLookup dataSourceLookup = new JndiDataSourceLookup();
DataSource dataSource = dataSourceLookup.getDataSource("java:jdbc/test");
return dataSource;
}
}
這是我的Application.java
文件:
@SpringBootApplication
public class DemoApplication {
public static void main(String[] args) {
SpringApplication.run(DemoApplication.class, args);
}
}
當我運行這一點,但我得到這個錯誤:
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'dataSource' defined in class path resource [com/example/AppConfig.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [javax.sql.DataSource]: Factory method 'dataSource' threw exception; nested exception is org.springframework.jdbc.datasource.lookup.DataSourceLookupFailureException: Failed to look up JNDI DataSource with name 'java:jdbc/test'; nested exception is javax.naming.NoInitialContextException: Need to specify class name in environment or system property, or as an applet parameter, or in an application resource file: java.naming.factory.initial

我做錯了什麼?
更新1: 這是我pom.xml
<build>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
<configuration>
<addResources>true</addResources>
</configuration>
</plugin>
</plugins>
</build>
因此,其他一切(用戶名,密碼,網址等)應該位於META-INF文件夾內的'context.xml'中?那麼如果我運行嵌入式tomcat呢?那麼我會在那裏放置那些信息? – Richard
在這種情況下,請在application.properties中指定url,username和password。 Spring Boot將自己創建datasouce。你甚至可以省略driver-class-name屬性,它可以通過url來確定。 –
