Mine Class:
@Path("/JerseyTesting")
public class JerseyTesting {
String name = "Maks";
String password = "pl000pl";
@GET
@Produces(MediaType.TEXT_PLAIN)
public String getName() {
    return name;
}
@GET
@Produces(MediaType.TEXT_PLAIN)
public String getPassword() {
    return password;
}

Mine web.xml page!

推荐答案

[[FATAL]资源模型具有用于HTTP方法GET的模棱两可(子)资源方法，并且在Java方法中由"@Consumes"和"@Produces"注释定义了输入mime类型. .JerseyTesting.getName()和公共java.lang.String jersey.JerseyTesting.getPassword()在匹配正则表达式/jerseytesting时.这两种方法产生并使用完全相同的mime类型，因此作为资源方法的调用将始终失败.

[[FATAL] A resource model has ambiguous (sub-)resource method for HTTP method GET and input mime-types as defined by"@Consumes" and "@Produces" annotations at Java methods public java.lang.String jersey.JerseyTesting.getName() and public java.lang.String jersey.JerseyTesting.getPassword() at matching regular expression /jerseytesting. These two methods produces and consumes exactly the same mime-types and therefore their invocation as a resource methods will always fail.;

您的资源方法不明确

@GET
@Produces(MediaType.TEXT_PLAIN)
public String getName() {
    return name;
}
@GET
@Produces(MediaType.TEXT_PLAIN)
public String getPassword() {
    return password;
}

Jersey不知道该选哪个.您将需要更改它们之一或两者的路径或媒体类型.您最有可能希望更改此特定情况的路径.像

Jersey will not know which one to pick. You will need to either change the path on one or both of them or the media type. Most likely you will want to change the path for this particular case. Something like

@GET
@Path("/name")
@Produces(MediaType.TEXT_PLAIN)
public String getName() {
    return name;
}
@GET
@Path("/password")
@Produces(MediaType.TEXT_PLAIN)
public String getPassword() {
    return password;
}
