Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name ‘org.springframework.web.servlet.resource.ResourceHttpRequestHandler#0’: Invocation of init method failed; nested exception is java.lang.IllegalStateException: WebApplicationObjectSupport instance [ResourceHttpRequestHandler [locations=[class path resource [WEB-INF/css/]], resolvers=[

[email protected]7a1e2d]]] does not run in a WebApplicationContext but in: [email protected]ee68d8: startup date [Sun Jul 30 18:48:01 CST 2017]; root of context hierarchy

解決辦法是新增如下註解：@WebAppConfiguration(“src/main/resources”)
註解括號的路徑是xml配置檔案的路徑

看報錯是靜態資源的Handler的ResourceHttpRequestHandler不能建立，正確程式碼如下：

package space.xxhui;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import org.springframework
 
.test.context.web.WebAppConfiguration;
import space.xxhui.POJO.User;
import space.xxhui.service.UserService;

import java.util.logging.Logger;

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration({ "classpath:spring/spring-config.xml"})
@WebAppConfiguration("src/main/resources")
public class UserDAOTest3 {

    @Autowired
    private UserService userService;

    private final Logger logger = Logger.getLogger(String.valueOf(getClass()));

    @Test
    public void TestUserSerivce(){
        logger.info("begin........");
        User user = new User();
        user.setName("Hitvz");
        user.setPwd("123456");
        User result = userService.checkUser(user);
        if(result!=null){
            System.out.println(result.toString());
        }
        logger.info("end........");
    }
}

報瞭如開頭引用的錯誤，這裡解釋一下：

@WebAppConfiguration註解在類上，
用來宣告載入的ApplicationContext是一個WebApplicationContext。
它的屬性指定的是Web資源的位置，預設為src/main/webapp

這裡把他修改為src/main/resources，指定配置檔案路徑

所以解決辦法就是指定到配置檔案的根路徑，這裡找不到根路徑，也就找不到Spring-config.xml的配置吧。所以加上更改根路徑的註解@WebAppConfiguration(“src/main/resources”)就好了。

大概意思就是要有根目錄：@WebAppConfiguration(“src/main/resources”)，接著從根目錄找到你的配置檔案：@ContextConfiguration({ “classpath:spring/spring-config.xml”})
