我怀疑使用Spring将对象注入到类中.我在我的项目中使用了这种代码:
@Resource // or @Autowired even @Inject
private PersonRepository personRepository;
然后在方法上正常使用它:
personRepository.save(p);
否则我在Spring示例中找到了注入构造函数:
private final PersonRepository personRepository;
@Autowired
public PersonController(PersonRepository personRepository) {
this.personRepository = personRepository;
}
那两个都是正确的？或者每个都有它的属性和用法？
使用Spring Security,我试图从我的CustomUserDetailsService上的loadUserByUsername方法返回我的CustomUser实例中的用户id,就像我获取带有Authentication的Name(get.Name())一样.谢谢你的任何提示!
这是我获取已登录用户的当前名称的方式:
Authentication authentication = SecurityContextHolder.getContext().getAuthentication();
String name = authentication.getName();
这是CustomUser
public class CustomUser extends User {
private final int userID;
public CustomUser(String username, String password, boolean enabled, boolean accountNonExpired,
boolean credentialsNonExpired,
boolean accountNonLocked,
Collection<? extends GrantedAuthority> authorities, int userID) {
super(username, password, enabled, accountNonExpired, credentialsNonExpired, accountNonLocked, authorities);
this.userID = userID;
}
}
和我的服务上的loadUserByUsername方法
@Override
public UserDetails loadUserByUsername(String s) throws UsernameNotFoundException {
Usuario u = usuarioDAO.getUsuario(s);
return new CustomUser(u.getLogin(), u.getSenha(), u.isAtivo(), u.isContaNaoExpirada(), u.isContaNaoExpirada(),
u.isCredencialNaoExpirada(), getAuthorities(u.getRegraByRegraId().getId()),u.getId()
);
}
我正在尝试用Data-JPA实现一个EntityGraph,因为使用QueryDslPredicateExecutor<T>暴露方法findAll(Predicate, Pageable)我需要的那个,我试图覆盖它注释@EntityGraph然后麻烦开始它抛出:
org.springframework.dao.InvalidDataAccessApiUsageException: org.hibernate.QueryException: query specified join fetching, but the owner of the fetched association was not present in the select list [FromElement{explicit,not a collection join,fetch join,fetch non-lazy properties,classAlias=appointment,role=com.physioclinic.entity.Appointment.createdBy,tableName=user,tableAlias=user5_,origin=appointment appointmen0_,columns={appointmen0_.createdBy_id ,className=com.physioclinic.entity.User}}] [select count(appointment)
from com.physioclinic.entity.Appointment appointment where lower(concat(concat(appointment.patient.person.name,?1),appointment.patient.person.surname)) like ?2 escape '!']; nested exception is java.lang.IllegalArgumentException: org.hibernate.QueryException: query specified join fetching, but the owner of the fetched association was not present in the select list [FromElement{explicit,not a collection join,fetch join,fetch non-lazy properties,classAlias=appointment,role=com.physioclinic.entity.Appointment.createdBy,tableName=user,tableAlias=user5_,origin=appointment appointmen0_,columns={appointmen0_.createdBy_id ,className=com.physioclinic.entity.User}}] …当我的用户使用一些Spring社交提供商(例如Twitter)成功登录时,我需要更改重定向URL.
我进入每一组***Url("")一个空指针异常有时设置它也不起作用
我到目前为止尝试设置:
public ProviderSignInController signInController(ConnectionFactoryLocator connectionFactoryLocator,
UsersConnectionRepository usersConnectionRepository) {
ProviderSignInController providerSignInController = new ProviderSignInController(connectionFactoryLocator,
usersConnectionRepository,
new CSignInAdapter(requestCache()));
providerSignInController.setPostSignInUrl("/home");
providerSignInController.setApplicationUrl("localhost:8080/home");
return providerSignInController;
}
我分别尝试了setPostSignInUrl和setApplicationUrl中的每一个.
还尝试过:
@Bean
public ConnectController connectController(ConnectionFactoryLocator connectionFactoryLocator,
ConnectionRepository connectionRepository) {
ConnectController connectController = new ConnectController(connectionFactoryLocator, connectionRepository);
connectController.addInterceptor(new TweetAfterConnectInterceptor());
connectController.setApplicationUrl("/home");
return connectController;
}
我正在使用Spring Social showcase和Security作为基础来做到这一点.如果需要,我发布HttpSecurity配置:
@Override
protected void configure(HttpSecurity http) throws Exception {
http
.formLogin()
.loginPage("/signin")
.loginProcessingUrl("/signin/authenticate")
.failureUrl("/signin?param.error=bad_credentials")
.defaultSuccessUrl("/home")
.and()
.csrf()
.and()
.logout()
.logoutUrl("/signout")
.deleteCookies("JSESSIONID")
.and()
.authorizeRequests()
.antMatchers("/admin/**", "/favicon.ico", "/resources/**", "/auth/**", "/signin/**", "/signup/**",
"/disconnect/facebook").permitAll()
.antMatchers("/**").authenticated()
.and()
.rememberMe() …我正在尝试实现Feign Clients从用户的服务获取我的用户信息,目前我正在请求oAuth2RestTemplate,它可以工作.但是现在我想改为Feign,但是我得到错误代码401可能是因为它没有携带用户令牌,所以有一种方法可以自定义,如果Spring支持Feign正在使用,那么我可以使用RestTemplate我自己的豆？
今天我正以这种方式实施
服务客户端
@Retryable({RestClientException.class, TimeoutException.class, InterruptedException.class})
@HystrixCommand(fallbackMethod = "getFallback")
public Promise<ResponseEntity<UserProtos.User>> get() {
logger.debug("Requiring discovery of user");
Promise<ResponseEntity<UserProtos.User>> promise = Broadcaster.<ResponseEntity<UserProtos.User>>create(reactorEnv, DISPATCHER)
.observe(Promises::success)
.observeError(Exception.class, (o, e) -> Promises.error(reactorEnv, ERROR_DISPATCHER, e))
.filter(entity -> entity.getStatusCode().is2xxSuccessful())
.next();
promise.onNext(this.client.getUserInfo());
return promise;
}
和客户
@FeignClient("account")
public interface UserInfoClient {
@RequestMapping(value = "/uaa/user",consumes = MediaTypes.PROTOBUF,method = RequestMethod.GET)
ResponseEntity<UserProtos.User> getUserInfo();
}
我正在学习EmberJS,我试图搜索文档和内容,但到目前为止我无法正确实现组件和响应点击事件的动作,现在它只是在控制台中打印一些东西.我想获得点击的元素,这样我就可以改变它的风格和属性.我正在使用ember-cli 版本0.2.7生成的脚手架.遵循以下代码:
app/components/heart-like.js
import Ember from 'ember';
export default Ember.Component.extend({
actions:{
click: function (event) {
console.log(event); // undefined
console.log("Hello from component");
}
}
});
app/templates/components/heart-like.hbs
<div class="row">
<span {{action "click"}} class="pull-right" style="color: #B71C1C;"><i class="fa fa-2x fa-heart"></i></span>
</div>
我想在加载Spring上下文之前添加一些查找,理想情况是在Spring Cloud的引导阶段(当它查找Configuration Server,云连接器等时).如何让我的代码在该阶段执行？
我想要做的是查询Vault以获取我的所有数据库机密和api密钥并设置属性,我知道我可以使用Spring Cloud Config加密,但我喜欢强大的Vault框.(与我可以处理的Vault部分集成)
