Spring Boot post方法不起作用

Question

对于下面的控制器，我的“GET”方法有效，但我的 post 方法无效。错误是“不支持 POST 方法”

我的创建方法工作正常，但更新不起作用。

这是我测试的 curl 命令：

curl -H "Content-Type: application/json" -X POST -d '[{ 编号：2， title: "我的第一条笔记标题更新", 注意：“我的第一个笔记更新”， 创建时间：1461737231000， 上次更新时间：1461737231000 } ]' -u "a@a.a":a localhost:8080/update

@RestController
public class GotPrintController {

    @Autowired
    private NotesRepository notesRepository;

    @Autowired
    private UserRepository userRepository;

    @RequestMapping("/createnotes")
    @Transactional
    public Notes create() {
        Authentication auth = SecurityContextHolder.getContext().getAuthentication();
        System.out.println("auth.getName::"+auth.getName());
        Notes notes = new Notes();
        notes.setCreateTime(new Date());
        notes.setLastUpdateTime(new Date());
        notes.setNote("My First Note");
        notes.setTitle("My first note title");
        notesRepository.save(notes);
        return notes;
    }


    @RequestMapping("/readnotes")
    @Transactional
    public List<Notes> read(){
        Authentication auth = SecurityContextHolder.getContext().getAuthentication();
        System.out.println("auth.getName::"+auth.getName());
        User users = userRepository.findByEmailId(auth.getName());
        List<Notes> notes = (List<Notes>) users.getNotes();
        return notes;
    }

    @RequestMapping(value="/delete/{id}/", method=RequestMethod.POST)
    @Transactional
    public String delete(@PathVariable Integer id){
        Authentication auth = SecurityContextHolder.getContext().getAuthentication();
        System.out.println("auth.getName::"+auth.getName());
        User users = userRepository.findByEmailId(auth.getName());
        List<Notes> notes = (List<Notes>) users.getNotes();
        for (Notes notes2 : notes) {
            if(notes2.getId() == id){
                notesRepository.delete(id);
                return "success";
            }
        }
        return "failure";

    }

    @RequestMapping(value="/update", method=RequestMethod.POST,headers = "Content-type: application/*")
    @Transactional
    public ResponseEntity<?> update(@RequestBody Notes note){
        Authentication auth = SecurityContextHolder.getContext().getAuthentication();
        System.out.println("auth.getName::"+auth.getName());
        User users = userRepository.findByEmailId(auth.getName());
        List<Notes> notes = (List<Notes>) users.getNotes();
        for (Notes notes2 : notes) {
            if(note.getId() == notes2.getId()){
                // note belongs to user update it
                notesRepository.save(note);
                return new ResponseEntity<>(note, HttpStatus.OK);
            }
        }
        return new ResponseEntity<>("", HttpStatus.NO_CONTENT); 
    }

}

这是尝试从 curl 热 POST 方法时的日志

2016-04-27 13:15:36.927 INFO 14755 --- [main] com.gotprint.GotprintApplication：在 18.481 秒内启动 GotprintApplication（JVM 运行时间为 23.399） 2016-04-27 13:15:47.298 INFO 14755 --- [nio-8080-exec-1] o.a.c.c.C.[Tomcat].[localhost].[/]：初始化 Spring FrameworkServlet 'dispatcherServlet' 2016-04-27 13:15:47.298 INFO 14755 --- [nio-8080-exec-1] os.web.servlet.DispatcherServlet：FrameworkServlet 'dispatcherServlet'：初始化开始 2016-04-27 13:15:47.336 INFO 14755 --- [nio-8080-exec-1] os.web.servlet.DispatcherServlet：FrameworkServlet 'dispatcherServlet'：初始化在 38 毫秒内完成 2016-04-27 13:15:47.433 WARN 14755 --- [nio-8080-exec-1] os.web.servlet.PageNotFound：不支持请求方法“POST”

这是我的实体类：

@Entity
public class Notes implements Serializable{

    /**
     * 
     */
    private static final long serialVersionUID = 1L;

    @Id
    @GeneratedValue(strategy=GenerationType.IDENTITY)
    @Column(name = "id")  
    private int id;

    @Column(name = "title")  
    private String title;

    @Column(name = "note")
    private String note; 

    @Column(name = "createTime")  
    private Date createTime;

    @Column(name = "lastUpdateTime")  
    private Date lastUpdateTime;

    public int getId() {
        return id;
    }

    public void setId(int id) {
        this.id = id;
    }

    public String getTitle() {
        return title;
    }

    public void setTitle(String title) {
        this.title = title;
    }

    public String getNote() {
        return note;
    }

    public void setNote(String note) {
        this.note = note;
    }

    public Date getCreateTime() {
        return createTime;
    }

    public void setCreateTime(Date createTime) {
        this.createTime = createTime;
    }

    public Date getLastUpdateTime() {
        return lastUpdateTime;
    }

    public void setLastUpdateTime(Date lastUpdateTime) {
        this.lastUpdateTime = lastUpdateTime;
    }

只需删除

headers = "Content-type: application/*"

如果您想接受特定的内容类型，请使用 RequestMapping 注解的 consumes 属性。

或者你想使用 headers 属性的语法是：

headers = "Content-type=application/*"
