Spring MVC 400 Bad Request Ajax(Spring MVC 400 Bad Request Ajax)

我一直在Ajax上请求400 Bad Request。 我不知道这会有什么问题。 我在用着：

<dependency> <groupId>org.codehaus.jackson</groupId> <artifactId>jackson-mapper-asl</artifactId> <version>1.9.12</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>4.0.5.RELEASE</version> </dependency>

控制器：

@Controller("bookController") @RequestMapping("/book") public class BookControllerImpl implements BookController { @Autowired BookService bookService; @Override @RequestMapping(value = "/new", method = RequestMethod.GET) public String addBookToSystem(Model model) { model.addAttribute("book", new Book()); return "book/newBook"; } @Override @RequestMapping(value = "/new", method = RequestMethod.POST, produces = MediaType.APPLICATION_JSON_VALUE, consumes = MediaType.APPLICATION_JSON_VALUE) public @ResponseBody Book addBookToSystem(@RequestBody Book book) { book.setBookStatus(BookStatus.AWAITING); return bookService.get(bookService.save(book)); }

Ajax调用：

$(document).ready(function(){ $('#addBook').submit(function(event) { var ISBN = $('#ISBN').val(); var author = $('#author').val(); var description = $('#description').val(); var pages = $('#pages').val(); var publicationYear = $('#publicationYear').val(); var publisher = $('#publisher').val(); var title = $('#title').val(); var json = { "ISBN" : ISBN, "author" : author, "description" : description, "pages" : pages, "publicationYear" : publicationYear, "publisher" : publisher, "title" : title }; $.ajax({ url: $("#addBook").attr("action"), data: JSON.stringify(json), type: "POST", dataType: 'json', contentType: 'application/json', success: function(book) { var respContent = ""; respContent += "<span class='success'>Dodano "; respContent += book.title; respContent += " do listy ksiazek oczekujacych na zatwierdzenie!</span>"; $("#bookResponse").html(respContent); } }); event.preventDefault(); }); });

HTTP请求：

POST /ksiazka/book/new.json HTTP/1.1 Host: localhost:8080 Connection: keep-alive Content-Length: 100 Accept: application/json, text/javascript, */*; q=0.01 Origin: http://localhost:8080 X-Requested-With: XMLHttpRequest User-Agent: Mozilla/5.0 (Windows NT 6.2; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/38.0.2125.111 Safari/537.36 Content-Type: application/json Referer: http://localhost:8080/ksiazka/book/new Accept-Encoding: gzip,deflate Accept-Language: pl-PL,pl;q=0.8,en-US;q=0.6,en;q=0.4,pt;q=0.2 Cookie: SPRING_SECURITY_REMEMBER_ME_COOKIE=bWFjaWVqbWlzMkBnbWFpbC5jb206MTQxNzUzODc3ODU4NjpjYjY3YTZiMWYyMGJjODYyMDYxMDQyNDIyN2NmNjQ3Mg; JSESSIONID=c5a72acb3bd1a165f9c2d705a199

响应：

HTTP/1.1 400 Bad Request Server: GlassFish Server Open Source Edition 4.1 X-Powered-By: Servlet/3.1 JSP/2.3 (GlassFish Server Open Source Edition 4.1 Java/Oracle Corporation/1.8) Content-Language: Content-Type: text/html Date: Tue, 04 Nov 2014 19:49:08 GMT Connection: close Content-Length: 1105

任何想法如何解决这个问题？ 作为基础，我使用了本教程。 我搜索并阅读了400 Bad Request错误的大多数线程，但它没有解决我的问题。

编辑：图书课程：

Im getting 400 Bad Request on Ajax request all the time. I have no idea what's could go wrong with this. Im using:

<dependency> <groupId>org.codehaus.jackson</groupId> <artifactId>jackson-mapper-asl</artifactId> <version>1.9.12</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>4.0.5.RELEASE</version> </dependency>

Any ideas how to solve this? As a base I used this tutorial. I searched and read most of threads with 400 Bad Request error but it didn't solve my problem.

Edit: Book class:

@Entity @Table(name="Book") @Indexed public class Book { @Id @GeneratedValue(strategy = GenerationType.AUTO) @Column(name = "bookId") private Long id; @Column(nullable = false) @Field(index = Index.YES, analyze=Analyze.YES, store=Store.NO) private String title; @Column(nullable = false, unique = true) private String ISBN; @Column(nullable = false) @Field(index = Index.YES, analyze=Analyze.YES, store=Store.NO) private String author; private String publisher; @Column(length = 1000) private String description; private int publicationYear; private int pages; @Enumerated(EnumType.STRING) @Column(nullable = false) private BookStatus bookStatus; @ManyToMany(mappedBy = "booksWant", cascade = CascadeType.ALL) private List<User> user = new ArrayList<User>(0); @OneToMany(mappedBy = "book", cascade = CascadeType.ALL) private List<UserBook> bookList = new ArrayList<UserBook>(0); public Book(String title, String ISBN, String author, String publisher, String description, int publicationYear, int pages, BookStatus bookStatus) { this.title = title; this.ISBN = ISBN; this.author = author; this.publisher = publisher; this.description = description; this.publicationYear = publicationYear; this.pages = pages; this.bookStatus = bookStatus; } getters and setters }

最满意答案

我解决了我的问题。 以下是我为了使其工作所做的事情：首先，我改变了对jackson2的依赖

<dependency> <groupId>com.fasterxml.jackson.core</groupId> <artifactId>jackson-annotations</artifactId> <version>2.4.3</version> </dependency> <dependency> <groupId>com.fasterxml.jackson.core</groupId> <artifactId>jackson-core</artifactId> <version>2.4.3</version> </dependency> <dependency> <groupId>com.fasterxml.jackson.core</groupId> <artifactId>jackson-databind</artifactId> <version>2.4.3</version> </dependency>

然后我用@JsonProperty和@JsonIgnore注释我的Book类。 这是我更新的Book课程

@Entity @Table(name="Book") @Indexed public class Book { @Id @GeneratedValue(strategy = GenerationType.AUTO) @Column(name = "bookId") @JsonIgnore private Long id; @Column(nullable = false) @Field(index = Index.YES, analyze=Analyze.YES, store=Store.NO) @JsonProperty("title") private String title; @Column(nullable = false, unique = true) @JsonProperty("ISBN") private String ISBN; @Column(nullable = false) @Field(index = Index.YES, analyze=Analyze.YES, store=Store.NO) @JsonProperty("author") private String author; @JsonProperty("publisher") private String publisher; @Column(length = 1000) @JsonProperty("description") private String description; @JsonProperty("publicationYear") private int publicationYear; @JsonProperty("pages") private int pages; @Enumerated(EnumType.STRING) @Column(nullable = false) @JsonIgnore private BookStatus bookStatus; @ManyToMany(mappedBy = "booksWant", cascade = CascadeType.ALL) @JsonIgnore private List<User> user = new ArrayList<User>(0); @OneToMany(mappedBy = "book", cascade = CascadeType.ALL) @JsonIgnore private List<UserBook> bookList = new ArrayList<UserBook>(0); public Book(String title, String ISBN, String author, String publisher, String description, int publicationYear, int pages, BookStatus bookStatus) { this.title = title; this.ISBN = ISBN; this.author = author; this.publisher = publisher; this.description = description; this.publicationYear = publicationYear; this.pages = pages; this.bookStatus = bookStatus; } getters and setters }

I solved my problem. Here is what I did in order to make it work: Firstly I changed dependency to jackson2

<dependency> <groupId>com.fasterxml.jackson.core</groupId> <artifactId>jackson-annotations</artifactId> <version>2.4.3</version> </dependency> <dependency> <groupId>com.fasterxml.jackson.core</groupId> <artifactId>jackson-core</artifactId> <version>2.4.3</version> </dependency> <dependency> <groupId>com.fasterxml.jackson.core</groupId> <artifactId>jackson-databind</artifactId> <version>2.4.3</version> </dependency>

Then I annotated my Book class with @JsonProperty and @JsonIgnore. Here is my updated Book class

@Entity @Table(name="Book") @Indexed public class Book { @Id @GeneratedValue(strategy = GenerationType.AUTO) @Column(name = "bookId") @JsonIgnore private Long id; @Column(nullable = false) @Field(index = Index.YES, analyze=Analyze.YES, store=Store.NO) @JsonProperty("title") private String title; @Column(nullable = false, unique = true) @JsonProperty("ISBN") private String ISBN; @Column(nullable = false) @Field(index = Index.YES, analyze=Analyze.YES, store=Store.NO) @JsonProperty("author") private String author; @JsonProperty("publisher") private String publisher; @Column(length = 1000) @JsonProperty("description") private String description; @JsonProperty("publicationYear") private int publicationYear; @JsonProperty("pages") private int pages; @Enumerated(EnumType.STRING) @Column(nullable = false) @JsonIgnore private BookStatus bookStatus; @ManyToMany(mappedBy = "booksWant", cascade = CascadeType.ALL) @JsonIgnore private List<User> user = new ArrayList<User>(0); @OneToMany(mappedBy = "book", cascade = CascadeType.ALL) @JsonIgnore private List<UserBook> bookList = new ArrayList<UserBook>(0); public Book(String title, String ISBN, String author, String publisher, String description, int publicationYear, int pages, BookStatus bookStatus) { this.title = title; this.ISBN = ISBN; this.author = author; this.publisher = publisher; this.description = description; this.publicationYear = publicationYear; this.pages = pages; this.bookStatus = bookStatus; } getters and setters }
