我一直在 Ajax 请求上收到 400 Bad Request。我不知道这会出什么问题。我正在使用:
<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>
Controller :
@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();
});
});

有什么想法可以解决这个问题吗？ 作为基础，我使用 this教程。我搜索并阅读了大多数带有 400 Bad Request 错误的线程，但这并没有解决我的问题。

最佳答案
我解决了我的问题。为了让它发挥作用，我做了以下事情: 首先，我将依赖项更改为 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>
然后我用 @JsonProperty 和 @JsonIgnore 注释了我的 Book 类。这是我更新的 Book 类
@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
}
