关于 springboot 几种调用方式的困惑

[AngelFalls]

下面这三种方式都能实现功能
JwtLoginRequestSuccessHandler 与 JwtUserService 都已在 config 中注册为 Bean
请教各位大佬这三种方式的优缺点以及大佬们经常使用哪种方式
谢谢


[方式一]
public class JwtLoginRequestSuccessHandler implements AuthenticationSuccessHandler {
...

private JwtUserService jwtUserService;

public JwtLoginRequestSuccessHandler(JwtUserService jwtUserService) {
this.jwtUserService = jwtUserService;
}
...
}

[方式二]
public class JwtLoginRequestSuccessHandler implements AuthenticationSuccessHandler {
...

@Autowired
private JwtUserService jwtUserService;

...
}

[方式三]
public class JwtLoginRequestSuccessHandler implements AuthenticationSuccessHandler {
...

private JwtUserService jwtUserService;

@Autowired
public JwtLoginRequestSuccessHandler(JwtUserService jwtUserService) {
this.jwtUserService = jwtUserService;
}
...
}
