Java RESTWebService使用SpringBoot和jersey。错误：应用程序初始化期间，应用程序资源模型的验证失败

下面我将在Spring boot应用程序中使用Jersey创建REST web服务：

我在初始化时出错。我想不出是什么

当我输入时：

我得到这个错误：

此应用程序没有/error的显式映射，因此您可以看到 这是一种退路

2017年4月20日星期四12:57:24 WAT出现意外错误 （类型=内部服务器错误，状态=500）。验证 应用程序资源模型在应用程序期间失败 初始化。[[FATAL]未找到参数为的注入源 键入publicjavax.ws.rs.core.Response com.first.rest.test.controller.BookController.updateBook（java.lang.String，com.first.rest.test.model.Book） 在索引0处；source='ResourceMethod{httpMethod=PUT， consumedTypes=[application/json]，producedTypes=[]，suspended=false， suspendTimeout=0，suspendTimeoutUnit=毫秒， invocable=invocable{handler=ClassBasedMethodHandler{handlerClass=class com.first.rest.test.controller.BookController， handlerConstructors=[org.glassfish.jersey.server.model。HandlerConstructor@642e8d2e]}, definitionMethod=public javax.ws.rs.core.Response com.first.rest.test.controller.BookController.updateBook（java.lang.String，com.first.rest.test.model.Book）， parameters=[Parameter[type=class java.lang.String，source=oid， defaultValue=null]，参数[type=class] com.first.rest.test.model.Book，source=null，defaultValue=null]]， responseType=classjavax.ws.rs.core.Response}，nameBindings=[]}']

控制台里有这个

servlet com.first.rest.test.jersey配置

应用程序初始化。 [[FATAL]未找到public javax.ws.rs.core.Response类型参数的注入源

项目结构为：

课程： 主要应用程序类别：

   @SpringBootApplication
public class FirstRestApplication {
    public static void main(String[] args) {
        SpringApplication.run(FirstRestApplication.class, args);
    }

Jersey配置类：

@Configuration
@ApplicationPath("rest")
public class JerseyConfiguration extends ResourceConfig {
    public JerseyConfiguration() {

    }

    @PostConstruct
    public void setUp() {
        register(BookController.class);
        register(GenericExceptionMapper.class);
    }
}

图书管理员类：

 @Component
@Path("/books")
public class BookController {

    private BookService bookService;

    public BookController(BookService bookService) {
        this.bookService = bookService;
    }

    @GET
    @Produces("application/json")
    public Collection<Book> getAllBooks() {
        return bookService.getAllBooks();
    }

    @GET
    @Produces("application/json")
    @Path("/{oid}")
    public Book getBook(@PathParam("oid") String oid) {
        return bookService.getBook(oid);
    }

    @POST
    @Produces("application/json")
    @Consumes("application/json")
    public Response addBook(Book book) {
        bookService.addBook(book);
        return Response.created(URI.create("/" + book.getOid())).build();
    }

    @PUT
    @Consumes("application/json")
    @Path("/{oid}")
    public Response updateBook(@PathParam("oid") String oid, Book book) {
        bookService.updateBook(oid, book);
        return Response.noContent().build();
    }

    @DELETE
    @Path("/{oid}")
    public Response deleteBook(@PathParam("oid") String oid) {
        bookService.deleteBook(oid);
        return Response.ok().build();
    }

我看到一个问题，但它与错误无关。如果希望注入构造函数，则需要

@Autowired

或

@Inject

注入构造函数。错误是说问题在于

updateBook

方法；无法为请求注入字符串参数。我能看到这种情况的唯一方法是ng是如果

@PathParam

注释不是

javax.ws.rs.PathParam

。我见过有人不小心导入了

javax.websocket.server.PathParam

，但我在你的项目中没有看到这种依赖关系。我发现我也不小心使用了它！我会更正它并查看。谢谢。我对第一句话的理解也是错误的。Y根据，你不需要

@Autowired

。每天学习一些新东西：-）@peeskillet我现在使用jax-rs提供的

code

@PathParam

code

。导入软件包时需要有人注意！：）我花了很多时间寻找原因！

public class Book {

    private String oid;
    private String name;
    private String author;
    private Category category;

    public Book() {

    }

     public Book(String oid, String name, String author, Category category) {
            super();
            this.oid = oid;
            this.name = name;
            this.author = author;
            this.category = category;
        }

        public String getOid() {
