我正在使用Spring Cloud学习微服务，在此之前一切都很好。我的配置服务器似乎正在工作。我在github帐户中有application.properties，它会从github获取它们。我还可以在我的localhost:8888/application/default或application/master以及存储它们的硬盘上看到它们。所以看起来很好。我的配置服务器：pom:
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-config-server</artifactId>
</dependency>
主要类别：
@SpringBootApplication
@EnableConfigServer
public class ConfigServerApplication {
public static void main(String[] args) {
SpringApplication.run(ConfigServerApplication.class, args);
}
}
application.properties:
spring.application.name=config-server
server.port=8888
spring.cloud.config.server.git.uri=https://github.com/account-name/repoName.git
spring.cloud.config.server.git.username=xxx
spring.cloud.config.server.git.password=xxx
spring.cloud.config.server.git.clone-on-start=true
现在给客户。它不想启动，因为属性中的值为空。不过，当我将值放在本地时，它会起作用。pom:
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-config</artifactId>
</dependency>
两者都有：
<dependencyManagement>
<dependencies>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-dependencies</artifactId>
<version>${spring-cloud.version}</version>
<type>pom</type>
<scope>import</scope>
</dependency>
</dependencies>
</dependencyManagement>
我现在暂时删除了application.properties，客户端只有bootstrap.yml：
spring:
application:
name: users-ws
cloud:
config:
uri: http://localhost:8888
name: config-server
server:
port: 0

它来自这里：
@Configuration
@EnableWebSecurity
public class WebSecurity extends WebSecurityConfigurerAdapter {
private final Environment env;
private final UserService userService;
private final BCryptPasswordEncoder bCryptPasswordEncoder;
@Autowired
public WebSecurity(
Environment environment,
UserService userService,
BCryptPasswordEncoder bCryptPasswordEncoder) {
this.env = environment;
this.userService = userService;
this.bCryptPasswordEncoder = bCryptPasswordEncoder;
}
@Override
protected void configure(AuthenticationManagerBuilder auth) throws Exception {
auth.userDetailsService(userService).passwordEncoder(bCryptPasswordEncoder);
}
@Override
protected void configure(HttpSecurity http) throws Exception {
http
.csrf().disable()
.headers().frameOptions().disable().and()
.authorizeRequests().anyRequest().permitAll()
// .authorizeRequests().antMatchers("/**").hasIpAddress(env.getProperty("gateway.ip"))
.and().addFilter(getAuthenticationFilter());
}
private AuthenticationFilter getAuthenticationFilter() throws Exception {
AuthenticationFilter authenticationFilter = new AuthenticationFilter(userService, env, authenticationManager());
// authenticationFilter.setAuthenticationManager(authenticationManager());
authenticationFilter.setFilterProcessesUrl(env.getProperty("login.url.path"));
return authenticationFilter;
}
}
它无法在getAuthenticationFilter((方法中设置FilterProcessesUrl。我无法获得物业login.url.path。当然，如果我把它放到application.properties中，一切都很好。我看了三四个关于配置的教程。我做同样的事情，但什么都不起作用。如果你看到发生了什么事，我会很高兴得到帮助。
这不是问题，spring团队默认情况下会更改enable Bootstrap的默认值，所以这就是为什么如果降级或设置本地属性，它会起作用。
来自春云的解决方案：
默认情况下，spring cloud commons提供的引导不再启用。如果您的项目需要它，可以由属性或新的启动程序重新启用它。
- 要通过属性重新启用，请设置spring.cloud.bootstrap.enabled=true或spring.config.使用legacyprocessing=true。这些需要设置作为环境变量、java系统属性或命令行论点
- 另一种选择是包含新的springcloudstarter引导程序
更多详细信息
好的，明白了。从将spring-boot-ver从2.4.0改为2.2.6，将spring-cloud版本改为Hoxton，一切都开始了。SR9或6。新版本似乎有一些问题。也许他们在改变什么。
