angularjs向spring发布json

400错误请求 从JSJSON到spring mvc

我使用angular js创建登录页面模块

它从angular到spring转换为json格式

如何在运行400错误请求时接收错误代码

myjsp代码：

  <div id="showProjects" ng-controller="crescentGetProjects">

    <table>

    <tr><td>User Name</td><td><input type="text" id="pname" name="pname" ng-model="project.UserName"></td></tr>
    <tr><td>Password</td><td><input type="text" id="aname" name="aname" ng-model="project.Password"></td></tr>
    <tr><td><input type="hidden" ng-model="project.projectId" /></td>
    <td><input type="button" value="Save" ng-click="saveProjectDetails(project)"></td></tr>

    </table>
    </div>

控制器代码

@RequestMapping(value = "/register", method = RequestMethod.POST,consumes="application/json")
public @ResponseBody String registerUser(@RequestBody LoginEntity userModel,HttpServletRequest request) {
    String resp=null;
    try{
        System.out.println("$$$$$$$$$$ "+userModel.getUserName());
    crescentManager.LoginCheck(userModel);
    resp="success";
    }catch(Exception e){
        resp="fail";
        System.out.println(e);
    }
    return resp;

}

我的实体类是

@Entity
@Table(name="LOGININFO")
public class LoginEntity {
    @Id
    @Column(name="LOGINID")
    @GeneratedValue
    private Integer LoginId;

    @Column(name="USERNAME")
    private String UserName;

    @Column(name="PASSWORD")
    private String Password;

    public Integer getLoginId() {
        return LoginId;
    }

    public void setLoginId(Integer loginId) {
        LoginId = loginId;
    }

    public String getUserName() {

        return UserName;
    }

    public void setUserName(String userName) {
        UserName = userName;
        System.out.println("@@@@@@@@@@@@@@@username is settled in entity   "+userName);
    }

    public String getPassword() {
        return Password;
    }

    public void setPassword(String password) {
        Password = password;
    }


}

错误的请求

您可以发布Firebug或开发工具捕获的HTTP请求吗？另外，如果您提供SpringTry提供的错误日志输出，并遵循camel case变量名的约定，那就太好了。JsonParser需要getUserName（）的用户名变量名，而您的代码提供的是用户名。因此，这个400错误的请求错误。@RequestMapping（value=“research/api/register”像这样更改此错误将显示我更改了请求映射值WARN org.springframework.web.servlet.PageNotFound-在名为“login model”的DispatcherServlet中找不到URI为[/LoginTest/rest/research/api/register]的HTTP请求的映射

@Entity
@Table(name="LOGININFO")
public class LoginEntity {
    @Id
    @Column(name="LOGINID")
    @GeneratedValue
    private Integer LoginId;

    @Column(name="USERNAME")
    private String UserName;

    @Column(name="PASSWORD")
    private String Password;

    public Integer getLoginId() {
        return LoginId;
    }

    public void setLoginId(Integer loginId) {
        LoginId = loginId;
    }

    public String getUserName() {

        return UserName;
    }

    public void setUserName(String userName) {
        UserName = userName;
        System.out.println("@@@@@@@@@@@@@@@username is settled in entity   "+userName);
    }

    public String getPassword() {
        return Password;
    }

    public void setPassword(String password) {
        Password = password;
    }
