我尝试从Spring主页＆＃34; https://spring.io/guides/gs/rest-service/＆＃34;模拟RESTful Web服务。我能够得到给定示例的预期输出，所以我做了一点改进，即尝试从oracle数据库中获取一些计数并显示为响应的一部分，但它没有工作。
Maven编译工作正常，但是当我运行弹簧启动时，我收到以下错误，我不知道可能是什么原因。我是春天新手，有人能帮助我吗？
我的配置详情为
Mac 10.9
EclipseLuna 4.4.1
Java的8
maven3.2.1
春天3.6

如果您使用的是spring-boot，请在下面添加依赖项以使用自动配置
的pom.xml
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-jdbc</artifactId>
</dependency>
在你的application.properties
中spring.datasource.driver-class-name=oracle.jdbc.driver.OracleDriver
spring.datasource.url=jdbc:oracle:thin:@testserver.com:2126:QADBA9FU
spring.datasource.username=test
spring.datasource.password=password123
编辑1
在你的EmployeeController中删除它
ApplicationContext ctx = new FileSystemXmlApplicationContext("/Users/sijayaraman/Documents/workspace/luna/CopyofSpringRest/sbeans.xml");
EmployeeDao dao=(EmployeeDaoImpl)ctx.getBean("employeedao");
改为使用
@Autowired
private EmployeeDao dao;
另外，注释类
@Component
public class EmployeeDaoImpl ...
编辑02
从http://www.oracle.com/technetwork/database/enterprise-edition/jdbc-112010-090769.html下载ojdbc6.jar并安装在您的maven本地存储库中
mvn install:install-file -Dfile={Path/to/your/ojdbc.jar} -DgroupId=com.oracle -DartifactId=ojdbc6 -Dversion=11.2.0 -Dpackaging=jar
然后通过
更改您的oracle依赖项<dependency>
<groupId>com.oracle</groupId>
<artifactId>ojdbc6</artifactId>
<version>11.2.0</version>
</dependency>
答案 1 :(得分：1)
它可能不是您问题的根源，但您没有正确访问您的dao。 Spring的主要原则是依赖注入，这意味着Controller不应该得到它的DAO。相反，它应该是自动装配或在配置文件中设置。
然后你Controller看起来像这样：
@RestController
public class EmployeeController {
@Autowired
EmployeeDao dao;
@RequestMapping("/employee")
public Employee employee(@RequestParam(value="name") String name) {
System.out.println("Count="+dao.getTotalCount());
return new Employee(dao.getTotalCount(),name);
}
}
您需要将sbeans.xml添加到配置中。尝试添加
@ImportXml("classpath:sbeans.xml")到Application.java：
@SpringBootApplication
@ImportXml("classpath:sbeans.xml")
public class Application
或者更好的是在Java中重写sbeans.xml。
