即使在导入cxf.xml之后也没有定义名为'cxf'的bean

问题描述 投票：1回答：1

我尝试使用Apache CXF将我的一个方法公开为REST Web服务。当我尝试访问http://localhost:7080/CXFwithMaven/services/book/abc的web服务时，我收到以下错误。

我尝试在互联网上搜索，发现这通常发生在你不导入cxf等文件时

<import resource="classpath:META-INF/cxf/cxf.xml" />
<import resource="classpath:META-INF/cxf/cxf-servlet.xml" />

虽然我已导入文件，但我仍然得到相同的错误。

请参阅以下VO。 package sample.cxfwithspring;

import javax.xml.bind.annotation.XmlRootElement;

@XmlRootElement(name="Book")
public class BookVO {
    private String name;
    private String author;

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getAuthor() {
        return author;
    }

    public void setAuthor(String author) {
        this.author = author;
    }

}

这是我的服务。

package sample.cxfwithspring;

import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.PathParam;
import javax.ws.rs.Produces;

@Path("/book")
public interface BookService {

    @GET
    @Produces("application/xml")
    @Path("/{name}")
    public BookVO getBook(@PathParam("{name}") String name);

}

和serviceImpl

package sample.cxfwithspring;

public class BookServiceImpl implements BookService {

    public BookVO getBook(String name) {
        BookVO bookVO = new BookVO();
        bookVO.setAuthor("abc");
        bookVO.setName("Rest with CXF");
        return bookVO;
    }

}

请帮助我，因为我是Apache CXF的新手，并尝试在任何地方搜索，但无法找到解决方案。

事实证明，添加这两行就是问题所在

<import resource="classpath:META-INF/cxf/cxf.xml" />
<import resource="classpath:META-INF/cxf/cxf-servlet.xml" />

删除它们就可以了。 ：d
