spring boot admin的简单使用

 

admin-server项目

添加 spring-boot-admin-starter-server 的依赖。

	<parent>
		<groupId>org.springframework.boot</groupId>
		<artifactId>spring-boot-starter-parent</artifactId>
		<version>2.3.1.RELEASE</version>
		<relativePath /> <!-- lookup parent from repository -->
	</parent>


        <dependency>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-starter-web</artifactId>
		</dependency>

		<!-- https://mvnrepository.com/artifact/de.codecentric/spring-boot-admin-starter-server -->
		<dependency>
		    <groupId>de.codecentric</groupId>
		    <artifactId>spring-boot-admin-starter-server</artifactId>
		    <version>2.2.3</version>
		</dependency>
		
		<dependency>
		    <groupId>org.springframework.boot</groupId>
		    <artifactId>spring-boot-starter-actuator</artifactId>
		</dependency>
		

在admin-server项目的springboot启动类添加 @EnableAdminServer 注解。

 

admin-client-simple项目

添加依赖

		<!-- https://mvnrepository.com/artifact/de.codecentric/spring-boot-admin-starter-client -->
		<dependency>
		    <groupId>de.codecentric</groupId>
		    <artifactId>spring-boot-admin-starter-client</artifactId>
		    <version>2.2.3</version>
		</dependency>
		
		<dependency>
		    <groupId>org.springframework.boot</groupId>
		    <artifactId>spring-boot-starter-actuator</artifactId>
		</dependency>

 

修改对应配置，使其注册到amin-server上

spring.application.name=adminclientsimple

server.port=8768
server.servlet.session.timeout=3600s

spring.boot.admin.client.url=http://localhost:8769

management.endpoints.web.exposure.include=*
management.endpoint.healthshow-details=always

 

安全配置

在对应pom.xml中添加 spring boot security的依赖

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-security</artifactId>
</dependency>

admin-server端添加安全后需要添加配置

spring.security.user.name=admin
spring.security.user.password=admin

这样访问admin-server就需要密码了。

admin-client-simple同样设置也可以设置密码访问。

同时需要更好的控制安全访问需要编写控制配置

写一个配置类SecuritySecureConfig继承WebSecurityConfigurerAdapter，配置如下 ，根据需要修改。

@Configuration
public class SecuritySecureConfig extends WebSecurityConfigurerAdapter {

    private final String adminContextPath;

    public SecuritySecureConfig(AdminServerProperties adminServerProperties) {
        this.adminContextPath = adminServerProperties.getContextPath();
    }

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        // @formatter:off
        SavedRequestAwareAuthenticationSuccessHandler successHandler = new SavedRequestAwareAuthenticationSuccessHandler();
        successHandler.setTargetUrlParameter( "redirectTo" );

        http.authorizeRequests()
                .antMatchers( adminContextPath + "/assets/**" ).permitAll()
                .antMatchers( adminContextPath + "/login" ).permitAll()
                .anyRequest().authenticated()
                .and()
                .formLogin().loginPage( adminContextPath + "/login" ).successHandler( successHandler ).and()
                .logout().logoutUrl( adminContextPath + "/logout" ).and()
                .httpBasic().and()
                .csrf().disable();
        // @formatter:on
    }
}

 

四、使用注册中心自动注册结合配置

admin-server项目

在admin-server中引入注册中心的client的依赖：

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
</dependency>

在admin-server的配置中添加如下配置：

#eureka.instance.hostname=192.168.31.192
#eureka.client.register-with-eureka=false
#eureka.client.fetch-registry=false
#eureka.client.serviceUrl.defaultZone=http://192.168.31.192:8761/eureka/

eureka:
  client:
    registryFetchIntervalSeconds: 5
    service-url:
      defaultZone: ${EUREKA_SERVICE_URL:http://localhost:8761}/eureka/
  instance:
    leaseRenewalIntervalInSeconds: 10
    health-check-url-path: /actuator/health

一个是yaml，一个是properties按自己情况修改对应参数添加到配置里。

最后还需要在admin-server项目启动类上添加 @EnableDiscoveryClient 注解。

如果启用了security的还需要添加注册对应的安全信息。

eureka:
  instance:
    metadata-map:
      user.name: ${spring.security.user.name}
      user.password: ${spring.security.user.password}

 

admin-client-simple项目

引入注册中心的client的依赖：

        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
        </dependency>

写入对应配置：

#eureka.instance.hostname=192.168.31.192
#eureka.client.register-with-eureka=false
#eureka.client.fetch-registry=false
#eureka.client.serviceUrl.defaultZone=http://192.168.31.192:8761/eureka/


eureka:
  instance:
    leaseRenewalIntervalInSeconds: 10
    health-check-url-path: /actuator/health

  client:
    registryFetchIntervalSeconds: 5
    service-url:
      defaultZone: ${EUREKA_SERVICE_URL:http://localhost:8761}/eureka/

同样根据需求添加和修改对应的配置。
