找不到REST资源

因此,我正在尝试开发具有Java类名称“ Service.java”的Web应用程序,这是我的REST服务。

@Path("/service")
public class Service {

    @Context
    HttpServletRequest request;
    @Context
    ServletContext ctx;

    @GET
    @Path("/getJustAdministrators")
    @Produces(MediaType.APPLICATION_JSON)
    public Collection<Administrator> getJustAdministrators() {
        System.out.println("get administrators");
        return getAdministrators().getValues();
    }

    private Administrators getAdministrators() {
    Administrators administrators = (Administrators) ctx
            .getAttribute("administrators");
    if (administrators == null) {
        administrators = new Administrators(ctx.getRealPath(""));
        ctx.setAttribute("administrators", administrators);
    }
    return administrators;
}

链接到我的欢迎页面的main.js文件如下所示:

var rootURL1 = "../eTicket/rest/service/getJustAdministrators";

loadAdministrators();

function loadAdministrators() {
    console.log('loadAdministrators');
    $.ajax({
        type : 'GET',
        url : rootURL1,
        dataType : "json", // data type of response
        success : function(data) {
            alert(data);
        }
    });
}

我在“检查”中遇到这样的错误:

http://localhost:8080/eTicket/rest/service/getJustAdministrators 404(未找到)

我的web.xml文件如下所示:

为什么找不到我的资源方法?

您的子路径可能试图绑定到根,就像/ service一样。

@Path("/getJustAdministrators")

您可能想要:

@Path("getJustAdministrators")

或者:

@Path("./getJustAdministrators")

或更明确地说:

@Path("/service/getJustAdministrators")

您的servlet类的定义不正确:

<servlet-class>org.glassfish.jersey.servlet.ServletContainer</servlet-class>

它应该指向您的Service.java类。
