src/main/resources/custom.properties

emp.auth=false

Szeretnénk az azonosítást kikapcsolhatóvá tenni:

src/lan/zold/emp/CustomProperties.java

package lan.zold.emp;
 
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.context.annotation.Configuration;
 
@Configuration
@ConfigurationProperties(prefix = "emp")
public class CustomProperties {
    private String auth;
    public String getAuth() {
        return this.auth;
    }
    public void setAuth(String auth) {
        this.auth = auth;
    }
}

Injektáljuk a CustomProperties osztályt:

@Autowired
CustomProperties customProperties;

A store() metódus aláírást át kell írnunk, hogy a fejléc ne legyen kötelező.

public Employee store(
    @RequestBody Employee emp, 
    @RequestHeader(
        value="Authorization", 
	required=false) 
	String tokenHeader)

Az egész metódus:

@CrossOrigin
@PostMapping(path="/employees")
public Employee store(
    @RequestBody Employee emp, 
    @RequestHeader(
        value="Authorization", 
        required=false) 
        String tokenHeader) {
 
    String authOkStr = customProperties.getAuth();
    boolean authOk = Boolean.parseBoolean(authOkStr);
    Employee res = null;
    if(authOk) {
        String token = tokenHeader.replace("Bearer ", "");
        AuthController authController = new AuthController();
 
        try {
            String tokenOk = authController.checkToken(token);
            if(tokenOk.equals("tokenok")) {
                res = empRepository.save(emp);
            }else {
                String msg = "Hiba! A token nem megfelelő!";
                throw new IllegalArgumentException(msg);
            }
        } catch (Exception e) {
            System.err.println("Hiba! A token nem jó!");
        }
    }else {
        res = empRepository.save(emp);
    }
    return res;
}
