\"realm\" : \"spring-learn-integration-springboot-security-keycloak\", \"bearer-only\" : true, \"auth-server-url\" : \"http://localhost:8080/auth\", \"ssl-required\" : \"external\", \"resource\" : \"spring-learn-integration-springboot-security-keycloak-client\", \"verify-token-audience\" : true, \"use-resource-role-mappings\" : true, \"confidential-port\" : 0&#125; 配置用户 出于演示目的，我们创建2个具有2个不同角色的用户，以便我们验证授权是否有效。 首先，让我们创建一个具有admin角色的用户： 创建admin用户： 123./kcadm.sh create users -r spring-learn-integration-springboot-security-keycloak -s username=admin -s enabled=trueCreated new user with id '50c11a76-a8ff-42b1-80cb-d82cb3e7616d' 设置admin密码： 1./kcadm.sh update users/50c11a76-a8ff-42b1-80cb-d82cb3e7616d/reset-password -r spring-learn-integration-springboot-security-keycloak -s type=password -s value=admin -s temporary=false -n value: 用户密码 追加到admin角色中 1./kcadm.sh add-roles -r spring-learn-integration-springboot-security-keycloak --uusername=admin --cclientid spring-learn-integration-springboot-security-keycloak-client --rolename admin 注意：从不在生产中使用此方法，它仅用于演示目的！ 然后我们创建另一个用户，这次有角色user： 创建user用户： 123./kcadm.sh create users -r spring-learn-integration-springboot-security-keycloak -s username=user -s enabled=trueCreated new user with id '624434c8-bce4-4b5b-b81f-e77304785803' 设置user密码： 1./kcadm.sh update users/624434c8-bce4-4b5b-b81f-e77304785803/reset-password -r spring-learn-integration-springboot-security-keycloak -s type=password -s value=admin -s temporary=false -n 追加到user角色中： 1./kcadm.sh add-roles -r spring-learn-integration-springboot-security-keycloak --uusername=user --cclientid spring-learn-integration-springboot-security-keycloak-client --rolename user Rest服务 我们已经配置了Keycloak并准备使用，我们只需要一个应用程序来使用它！所以我们创建一个简单的Spring Boot应用程序。我会在这里使用maven构建项目： 12345678910111213141516171819202122232425262728293031323334353637383940414243444546474849505152535455565758596061626364656667686970717273747576777879808182&lt;?xml version=\"1.0\" encoding=\"UTF-8\"?&gt;&lt;project xmlns=\"http://maven.apache.org/POM/4.0.0\" xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xsi:schemaLocation=\"http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd\"&gt;

auth.authenticationProvider(keycloakAuthenticationProvider());&#125; 我们还需要为Keycloak设置会话策略，但是当我们创建无状态REST服务时，我们并不真的想要有会话，因此我们使用NullAuthenticatedSessionStrategy： 1234@Overrideprotected SessionAuthenticationStrategy sessionAuthenticationStrategy() &#123; return new NullAuthenticatedSessionStrategy();&#125; 通常，Keycloak Spring Security集成从keycloak.json文件中解析keycloak配置，但是我们希望有适当的Spring Boot配置，因此我们使用Spring Boot覆盖配置解析器： 1234@BeanKeycloakConfigResolver keycloakConfigResolver() &#123; return new KeycloakSpringBootConfigResolver();&#125; 然后我们配置Spring Security来授权所有请求： 1234567@Overrideprotected void configure(final HttpSecurity http) throws Exception &#123; super.configure(http); http .authorizeRequests() .anyRequest().permitAll();&#125; 最后，根据文档，我们阻止双重注册Keycloak的过滤器： 123456789101112131415@Beanpublic FilterRegistrationBean keycloakAuthenticationProcessingFilterRegistrationBean( final KeycloakAuthenticationProcessingFilter filter) &#123;

void print(String source);&#125; 创建Service接口的实现类JavaService和GuiceService，用于实现接口中的方法，代码如下 12345678910package com.edurt.sli.guice.multiple;public class JavaService implements Service &#123; @Override public void print(String source) &#123;

&lt;/configuration&gt; &lt;/plugin&gt; &lt;/plugins&gt; &lt;/build&gt;&lt;/project&gt; guice: guice就是我们核心要使用的依赖 构造函数注入 在Guice中我们可以通过将需要的实体信息通过构造函数直接注入到我们需要的任意地方，我们通过列举一个例子来实际说明。 创建com.edurt.sli.guice.sample文件夹，并在该文件夹下创建Service接口文件，用于添加我们需要测试的函数 12345678910package com.edurt.sli.guice.sample;import com.google.inject.ImplementedBy;@ImplementedBy(ServiceImpl.class)public interface Service &#123; void print(String source);&#125; 创建Service接口的实现类ServiceImpl，用于实现接口中的方法，代码如下 123456789package com.edurt.sli.guice.sample;public class ServiceImpl implements Service &#123; @Override public void print(String source) &#123; System.out.println(String.format(\"Hello Guice, %s\", source)); &#125;&#125; 创建用于测试注入的应用类Application，代码如下 123456789101112131415161718192021222324package com.edurt.sli.guice.sample;import com.google.inject.Guice;import com.google.inject.Inject;public class Application &#123; private Service service; @Inject public Application(Service service) &#123; this.service = service; &#125; public Service getService() &#123; return service; &#125; public static void main(String[] args) &#123; Application application = Guice.createInjector().getInstance(Application.class); application.service.print(\"Test\"); &#125;&#125; 我们运行程序输出 1Hello Guice, Test 这个示例很好理解，实际就是说我们将Service接口通过@Inject注入到了Application应用中。当然我们通过@ImplementedBy(ServiceImpl.class)实现了类似Service service = new ServiceImpl()的操作，不过每次会生成一个新的实例，如果需要单例模式的话，需要单独操作。 注意：在本次程序中我们并没有通过Module关联到Guice，方便我们快速测试应用等。我们无法通过非Guice容器进行注入，以下就是一个错误的示例static也是无法进行注入的 12345678910111213141516171819package com.edurt.sli.guice.sample;import com.google.inject.Inject;public class ApplicationCustom &#123; @Inject private Service service; public Service getService() &#123; return this.service; &#125; public static void main(String[] args) &#123; ApplicationCustom custom = new ApplicationCustom(); custom.getService().print(\"Test\"); &#125; &#125; 我们运行上述代码，会提示以下错误信息 12Exception in thread \"main\" java.lang.NullPointerException at com.edurt.sli.guice.sample.ApplicationCustom.main(ApplicationCustom.java:16) 这也就说明我们无法在非Guice容器中进行实例注入 多参数注入 上述实例我们只是注入了一个参数，那我们尝试一下多参数注入。 我们先书写另一个需要注入的服务和实现，PrintService代码如下 12345678910package com.edurt.sli.guice.sample;import com.google.inject.ImplementedBy;@ImplementedBy(PrintServiceImpl.class)public interface PrintService &#123; void print();&#125; 实现类ImplementedBy代码如下 12345678910package com.edurt.sli.guice.sample;public class PrintServiceImpl implements PrintService &#123; @Override public void print() &#123; System.out.println(\"print Service\"); &#125;&#125; 该服务我们只提供固定的输出字符串信息print Service，接下来我们进行对多参数注入，ApplicationMultiple代码如下 12345678910111213141516171819202122232425package com.edurt.sli.guice.sample;import com.google.inject.Guice;import com.google.inject.Inject;import lombok.Data;@Datapublic class ApplicationMultiple &#123; private Service service; private PrintService printService; @Inject public ApplicationMultiple(Service service, PrintService printService) &#123; this.service = service; this.printService = printService; &#125; public static void main(String[] args) &#123; ApplicationMultiple multiple = Guice.createInjector().getInstance(ApplicationMultiple.class); multiple.getPrintService().print(); multiple.getService().print(\"Multiple\"); &#125;&#125; 运行程序后，输出以下结果 12print ServiceHello Guice, Multiple 我们使用一个@Inject也能实现多个参数的实例注入，当然还支持Set方式注入，只需要在参数的set方法上增加@Inject注解即可实现，这里我们不多做叙述，可自行实验。 static静态参数注入 我们说过无法注入通过static属性直接进行注入使用，方法总是很多的，Guice提供了以下static注入方式 12345678910111213141516package com.edurt.sli.guice.sample;import com.google.inject.Guice;import com.google.inject.Inject;public class ApplicationStatic &#123; @Inject private static Service service; public static void main(String[] args) &#123; Guice.createInjector(binder -&gt; binder.requestStaticInjection(ApplicationStatic.class)); ApplicationStatic.service.print(\"Static\"); &#125;&#125; 在代码中我们没有向以上两个示例直接使用Guice获取实例，而是使用了binder.requestStaticInjection方式进行了注入，这个是和static属性息息相关的，当我们注入static属性的时候要告知Guice我们具体使用static属性的父类，这样Guice才可以帮我们注入进来。 细心的话会想到我们既然使用binder.requestStaticInjection方式注入static属性，那么非static属性是不是也可以通过类似的方式注入？ 答案是可以的，非static的属性我们需要通过binder.requestInjection(Type);方式注入，实例如下： 1234567891011121314151617package com.edurt.sli.guice.sample;import com.google.inject.Guice;import com.google.inject.Inject;public class ApplicationBinder &#123; @Inject private Service service; public static void main(String[] args) &#123; ApplicationBinder applicationBinder = new ApplicationBinder(); Guice.createInjector(binder -&gt; binder.requestInjection(applicationBinder)); applicationBinder.service.print(\"Test\"); &#125;&#125; 当然我们还可以通过Guice.createInjector().injectMembers(new Object());方式注入。 注意我们需要创建一个主类的实例才可以注入，使用ApplicationBinder.class是无法注入的 打包文件部署 打包数据 1mvn clean package -Dmaven.test.skip=true -X 运行打包后的文件即可 1java -jar target/guice-binder-constructor-1.0.0.jar 源码地址 GitHub","categories":[{"name":"Java","slug":"Java","permalink":"https://learn-programming.edurt.io/categories/Java/"},{"name":"Guice","slug":"Java/Guice","permalink":"https://learn-programming.edurt.io/categories/Java/Guice/"}],"tags":[{"name":"Guice","slug":"Guice","permalink":"https://learn-programming.edurt.io/tags/Guice/"},{"name":"Java","slug":"Java","permalink":"https://learn-programming.edurt.io/tags/Java/"}]},{"title":"Guice依赖注入(基础版)","slug":"Java/Guice/binder-multiple","date":"2020-10-09T10:36:09.000Z","updated":"2020-10-09T10:36:48.518Z","comments":true,"path":"2020/10/09/Java/Guice/binder-multiple.html","link":"","permalink":"https://learn-programming.edurt.io/2020/10/09/Java/Guice/binder-multiple.html","excerpt":"","text":"本教程主要详细讲解Guice的一些基本注入方式,通过该简单教程让我们可以快速使用Guice进行简单系统化开发,后续我们会更深入讲解更多模块,如果还不了解Guice大家可以先去网上自行了解一下. 基础环境 技术 版本 Java 1.8+ Guice 4.2.3 初始化项目 初始化项目 1mvn archetype:generate -DgroupId=com.edurt.sli.guice -DartifactId=guice-basic -DarchetypeArtifactId=maven-archetype-quickstart -Dversion=1.0.0 -DinteractiveMode=false 修改pom.xml增加Guice依赖 123456789101112131415161718192021222324252627282930313233343536373839404142434445&lt;?xml version=\"1.0\" encoding=\"UTF-8\"?&gt;&lt;project xmlns=\"http://maven.apache.org/POM/4.0.0\" xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xsi:schemaLocation=\"http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd\"&gt;

@Override protected void configure() &#123; &#125;&#125; Guice中的绑定模型和Spring中的一样简单,我们通过绑定可以提供给程序任意注入类. 绑定我们需要的Module只需要继承Guice中的com.google.inject.AbstractModule即可,在configure方法中实现我们需要的绑定信息. 在com.edurt.sli.guice.sample目录下构建GuiceBasicService接口类,内容如下 1234567package com.edurt.sli.guice.sample;public interface GuiceBasicService &#123;

public void print(String output) &#123; System.out.println(String.format(\"print %s\", output)); &#125;&#125; 接下来修改GuiceBasicModule将我们定义的服务进行绑定,代码如下 123456789101112package com.edurt.sli.guice.sample;import com.google.inject.AbstractModule;public class GuiceBasicModule extends AbstractModule &#123; @Override protected void configure() &#123; bind(GuiceBasicService.class).to(GuiceBasicServiceImpl.class); &#125;&#125; 这样我们就很快的绑定了一个服务,类似于Spring中的@Bean方式 bind标志我们需要绑定的类,to标志我们绑定的实现类 在com.edurt.sli.guice.sample目录下构建GuiceBasicApplication类文件用于我们测试代码,在文件输入以下内容 123456789101112131415package com.edurt.sli.guice.sample;import com.google.inject.Guice;import com.google.inject.Injector;public class GuiceBasicApplication &#123;
