cloud - Spring Cloug 配置客户端不从配置服务器获取属性
问题描述
我正在使用 Spring Cloud 学习微服务，到目前为止一切正常。看来我的配置服务器正在工作。我的 git hub 帐户中有我的 application.properties，它从 Git Hub 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驱动器上看到它们。所以看起来不错。我的配置服务器：pom：
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-config-server</artifactId>
</dependency>
主类：
@SpringBootApplication
@EnableConfigServer
public class ConfigServerApplication {
public static void main(String[] args) {
SpringApplication.run(ConfigServerApplication.class, args);
}
}
应用程序属性：
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
现在为客户。它不想启动，导致属性中的空值。不过，当我将值放在本地时它会起作用。起居室：
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-config</artifactId>
</dependency>
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>
我现在删除了 application.properties 并且在客户端只有 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;
}
}
它不能在 getAuthenticationFilter() 方法中设置 FilterProcessesUrl。我不能得到财产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，没有任何工作。如果您看到发生了什么，我会很高兴为您提供帮助。
解决方案
好的，我知道了。从将 spring boot 版本从 2.4.0 更改为较低的 2.2.6 并将 spring 云版本更改为 Hoxton.SR9 或 6，一切都开始了。新版好像有点问题 也许他们正在改变一些东西。
