1.生成jwt令牌

在认证工程创建测试类，测试jwt令牌的生成与验证。

//生成一个jwt令牌
@Test
public void testCreateJwt(){
    //证书文件
    String key_location = "xc.keystore";
    //密钥库密码
    String keystore_password = "xuechengkeystore";
    //访问证书路径
    ClassPathResource resource = new ClassPathResource(key_location);
    //密钥工厂
    KeyStoreKeyFactory keyStoreKeyFactory = new KeyStoreKeyFactory(resource,
keystore_password.toCharArray());
    //密钥的密码，此密码和别名要匹配
String keypassword = "xuecheng";
    //密钥别名
    String alias = "xckey";
    //密钥对（密钥和公钥）
    KeyPair keyPair = keyStoreKeyFactory.getKeyPair(alias,keypassword.toCharArray());
    //私钥
    RSAPrivateKey aPrivate = (RSAPrivateKey) keyPair.getPrivate();
    //定义payload信息
    Map<String, Object> tokenMap = new HashMap<>();
    tokenMap.put("id", "123");
    tokenMap.put("name", "mrt");
    tokenMap.put("roles", "r01,r02");
    tokenMap.put("ext", "1");
    //生成jwt令牌
    Jwt jwt = JwtHelper.encode(JSON.toJSONString(tokenMap), new RsaSigner(aPrivate));
    //取出jwt令牌
    String token = jwt.getEncoded();
    System.out.println("token="+token);
}

2.验证jwt令牌

//资源服务使用公钥验证jwt的合法性，并对jwt解码
    @Test
    public void testVerify(){
        //jwt令牌
        String token

        //校验jwt
        Jwt jwt = JwtHelper.decodeAndVerify(token, new RsaVerifier(publickey));

        System.out.println(encoded);
