我有一个使用spring boot运行的应用程序。我需要使用hibernate。我得到了这个例外。我不确定我应该拥有的配置文件。因为我已经搜索了很多新的东西：我有pom.xml，我不知道我是否应该使用web.xml。我需要尽快让它工作。这是我的例外：
org.springframework.beans.factory.UnsatisfiedDependencyException:

我有log4j.properties：
# Direct log messages to stdout
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.Target=System.out
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d{ABSOLUTE} %5p %c{1}:%L - %m%n
# Root logger option
log4j.rootLogger=DEBUG,stdout
和Application.properties：
#
## Database configuration
#
spring.datasource.url= jdbc:mysql://localhost:3307/spring
spring.datasource.username= spring
spring.datasource.password= spring
spring.datasource.driverClassName= com.mysql.jdbc.Driver
spring.view.prefix=/WEB-INF/jsp/
spring.view.suffix=.jsp
这是service.configuration类，我认为可能有问题：
@ComponentScan
@Configuration
@EnableJpaRepositories
public class ServiceConfiguration {
public static final String CRM_NAME = "crm";
/**
* The root directory to which all uploads for the application are uploaded.
*/
public static final File CRM_STORAGE_DIRECTORY = new File(
System.getProperty("user.home"), CRM_NAME);
/**

* of staging directory

/**

答案 0 :(得分：0)
String url = "<url_link for http or https>";
int timeout = 30*1000; // 30 seconds
Proxy proxy = new Proxy(Proxy.Type.HTTP, new InetSocketAddress("<proxy_host>", <proxy_port>));
// if need to auth for proxy
Authenticator authenticator = new Authenticator() {
public PasswordAuthentication getPasswordAuthentication() {
return (new PasswordAuthentication("<user>",
"<password>".toCharArray()));
}
};
Authenticator.setDefault(authenticator);
// open connection using proxy directly for this connection
// if not, setting in the JVM startup argus or using System.setProperty for app global scope
HttpURLConnection conn = new URL(url).openConnection(proxy); // Also HttpsURLConnection
conn.setConnectTimeout(timeout); // set Timeout
您错过了@ComponentScan
@Configuration(basePackages = {"<Specify your base package here>"})
@EnableJpaRepositories
public class ServiceConfiguration {

}
