Spring Boot启动REST服务失败

Question

Spring Boot启动REST服务失败

3

我尝试模拟来自Spring主页 "https://spring.io/guides/gs/rest-service/" 的RESTful Web服务。我能够获得给定示例的预期输出，因此我进行了一些改进，即尝试从Oracle数据库中获取一些计数并将其显示为响应的一部分，但它没有起作用。

Maven编译正常，但当我运行Spring Boot时，我遇到了以下错误，我不知道原因是什么。我对Spring很陌生，有人能帮帮我吗？

我的配置详细信息如下： Mac 10.9 EclipseLuna 4.4.1 Java-8 maven3.2.1 spring 3.6

Spring Boot 错误：

可能这不是你问题的根源，但是你没有正确访问你的dao。Spring的主要原则是依赖注入，这意味着Controller不应该获得它的DAO，而应该在配置文件中自动装配或设置。

然后你的Controller会像这样:

@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。尝试在 Application.java 中添加 @ImportXml("classpath:sbeans.xml")：

@SpringBootApplication
@ImportXml("classpath:sbeans.xml") 
public class Application

或者更好的方法是用Java重写。

如果您正在使用spring-boot，为了使用自动配置，请添加以下依赖项 pom.xml

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-jdbc</artifactId>
</dependency>

在你的application.properties文件中：

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

请在您的EmployeeController中删除此内容。

ApplicationContext ctx = new FileSystemXmlApplicationContext("/Users/sijayaraman/Documents/workspace/luna/CopyofSpringRest/sbeans.xml");
EmployeeDao dao=(EmployeeDaoImpl)ctx.getBean("employeedao");

改用

@Autowired
private EmployeeDao dao;

此外，还要注释类。

@Component
public class EmployeeDaoImpl ...

从http://www.oracle.com/technetwork/database/enterprise-edition/jdbc-112010-090769.html下载ojdbc6.jar，并安装在您的Maven本地仓库中。

mvn install:install-file -Dfile={Path/to/your/ojdbc.jar} -DgroupId=com.oracle -DartifactId=ojdbc6 -Dversion=11.2.0 -Dpackaging=jar

然后通过以下方式更改您的Oracle依赖：

<dependency>
    <groupId>com.oracle</groupId>
    <artifactId>ojdbc6</artifactId>
    <version>11.2.0</version>
</dependency>
