NoSuchBeanDefinitionException:找不到符合条件的bean类型
NoSuchBeanDefinitionException:找不到符合条件的bean类型
提问于 2015-09-15 00:06:56
我正在制作一个Spring + Hibernate + Maven项目。在基本登录后，我尝试使用注释，但被困在那里。我已经尝试了一切可能的方法，仍然无法摆脱这个错误NoSuchBeanDefinitionException:没有类型为依赖项找到的限定bean
以下是配置：
控制器
package com.pnpjunction.thefloorplan.controller;
@Controller
@RequestMapping(value = "/ProceedWithLogin")
public class LoginController {
@Autowired
AdminService adminService;
@RequestMapping(value = "/uthja", method = RequestMethod.POST)
public ModelAndView doLogin(@RequestParam("name") String name,
@RequestParam("password") String password) {
String message = "";
if (adminService.doAuthenticate(name, password)) {
// Authentication successful
message = "Welcome!!";
} else {
// Authentication failed
message = "Not Welcome!!";
}
return new ModelAndView("results", "message", message);
}}服务：
package com.pnpjunction.thefloorplan.service;
public interface AdminService {
boolean doAuthenticate(String name, String password);
}ServiceImplementation
package com.pnpjunction.thefloorplan.serviceimpl;
@Service("AdminServiceImpl")
public class AdminServiceImpl implements AdminService {
@Override
public boolean doAuthenticate(String name, String password) {
return true;
}}web.xml

任何帮助都将不胜感激。

由于服务的实现在包com.pnpjunction.thefloorplan.serviceimpl中，所以必须将该包添加到组件扫描中。因此，在Spring中添加<context:component-scan base-package="com.pnpjunction.thefloorplan.serviceimpl" />。

您需要将@Service("AdminServiceImpl")修改为@Service("adminService")，因为它正在寻找名称为adminService的bean。

所有要自动读取的bean必须在组件扫描过程中可见的包内，可以使用注释或上下文条目。
context:component-scan base-package="com.pnpjunction.thefloorplan"/>或
@ComponentScan(basePackages = {"com.pnpjunction.thefloorplan"} )页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
