2.2. 创建 JwtClaimsBuilder 并设置声明

// Create an empty builder and add some claims
JwtClaimsBuilder builder1 = Jwt.claims();
builder1.claim("customClaim", "custom-value").issuer("https://issuer.org");
// Alternatively, start with claims directly:
// JwtClaimsBuilder builder1 = Jwt.upn("Alice");

// Create a builder from an existing claims file

// Create a builder from a map of claims
JwtClaimsBuilder builder3 = Jwt.claims(Collections.singletonMap("customClaim", "custom-value"));

// Create a builder from a JsonObject
