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;
}
}

[[FATAL]资源模型具有HTTP方法GET的模糊(子)资源方法和由Java方法public java.lang.String jersey.JerseyTesting中的"@Consumes"和"@Produces"注释定义的输入mime类型. getName()和public java.lang.String jersey.JerseyTesting.getPassword()匹配正则表达式/ jerseytesting.这两个方法生成并使用完全相同的mime类型,因此它们作为资源方法的调用将始终失败.

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;
}

泽西岛不知道选哪一个.您需要更改其中一个或两个路径或媒体类型的路径.您很可能想要更改此特定案例的路径.就像是

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