新增案例子系统（hello），使用工具：IDEA

创建微服务子系统

1、右键【qingfeng-server】->New->Module…
image.png
2、选择Maven，新建maven子模块项目
image.png
3、父节点选择：qingfeng-server，子模块名称：qingfeng-server-hello
image.png
4、选择本地的maven安装地址及相关配置，点击完成。
image.png
5、创建完成后会在qingfeng-server中显示刚刚创建的子业务系统：qingfeng-server-hello
image.png

完善微服务子系统

1、基础调整

删除test下的AppTest.java ，在src/main下新建：resources 文件夹。
image.png

2、配置pom.xml

因为qingfeng-server-hello继承与qingfeng-server父模块，在父模块中的配置的jar会继承到子模块中，所以子模块设置如下：

  1. <?xml version="1.0" encoding="UTF-8"?>
  3. <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  4.          xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
  5.   <parent>
  6.     <artifactId>qingfeng-server</artifactId>
  7.     <groupId>com.qingfeng</groupId>
  8.     <version>1.0-SNAPSHOT</version>
  9.   </parent>
  10.   <modelVersion>4.0.0</modelVersion>
  12.   <artifactId>qingfeng-server-hello</artifactId>
  13.   <name>qingfeng-server-hello</name>
  15.   <description>qingfeng-Server-Hello案例服务模块</description>
  17.   <build>
  18.     <plugins>
  19.       <plugin>
  20.         <groupId>org.springframework.boot</groupId>
  21.         <artifactId>spring-boot-maven-plugin</artifactId>
  22.       </plugin>
  23.     </plugins>
  24.   </build>
  25. </project>

3、修改主入口文件

将App.java ,修改成：ServerHelloApplication.java
@SpringBootApplication
@EnableGlobalMethodSecurity(prePostEnabled = true)

开启springsecurity
@EnableCloudApplication #自定义注入集合，如下图：
image.png

  1. package com.qingfeng;
  3. import com.qingfeng.annotation.EnableCloudApplication;
  4. import org.springframework.boot.SpringApplication;
  5. import org.springframework.boot.autoconfigure.SpringBootApplication;
  6. import org.springframework.security.config.annotation.method.configuration.EnableGlobalMethodSecurity;
  8. /**
  9.  * @ProjectName ServerHelloApplication
  10.  * @author Administrator
  11.  * @version 1.0.0
  12.  * @Description TODO
  13.  * @createTime 2021/4/19 0019 12:49
  14.  */
  15. @SpringBootApplication
  16. @EnableGlobalMethodSecurity(prePostEnabled = true)
  17. @EnableCloudApplication
  18. public class ServerHelloApplication {
  20.     public static void main(String[] args) {
  21.         SpringApplication.run(ServerHelloApplication.class, args);
  22.     }
  24. }

4、新建ServerHelloResourceServerConfigure

在com.qingfeng下新建：configure目录，新增：ServerHelloResourceServerConfigure.java （权限配置）

  1. package com.qingfeng.configure;
  3. import com.qingfeng.handler.MyAccessDeniedHandler;
  4. import com.qingfeng.handler.MyAuthExceptionEntryPoint;
  5. import org.springframework.beans.factory.annotation.Autowired;
  6. import org.springframework.context.annotation.Configuration;
  7. import org.springframework.security.config.annotation.web.builders.HttpSecurity;
  8. import org.springframework.security.oauth2.config.annotation.web.configuration.EnableResourceServer;
  9. import org.springframework.security.oauth2.config.annotation.web.configuration.ResourceServerConfigurerAdapter;
  10. import org.springframework.security.oauth2.config.annotation.web.configurers.ResourceServerSecurityConfigurer;
  12. /**
  13.  * @ProjectName ServerHelloResourceServerConfigure
  14.  * @author Administrator
  15.  * @version 1.0.0
  16.  * @Description TODO
  17.  * @createTime 2021/4/19 0019 12:54
  18.  */
  19. @Configuration
  20. @EnableResourceServer
  21. public class ServerHelloResourceServerConfigure extends ResourceServerConfigurerAdapter {
  23.     @Autowired
  24.     private MyAccessDeniedHandler accessDeniedHandler;
  25.     @Autowired
  26.     private MyAuthExceptionEntryPoint exceptionEntryPoint;
  28.     @Override
  29.     public void configure(HttpSecurity http) throws Exception {
  30.         http.csrf().disable()
  31.                 .requestMatchers().antMatchers("/**")
  32.                 .and()
  33.                 .authorizeRequests().antMatchers("/actuator/**").permitAll()
  34.                 .and()
  35.                 .authorizeRequests()
  36.                 .antMatchers("/**").authenticated();
  37.     }
  39.     @Override
  40.     public void configure(ResourceServerSecurityConfigurer resources) {
  41.         resources.authenticationEntryPoint(exceptionEntryPoint)
  42.                 .accessDeniedHandler(accessDeniedHandler);
  43.     }
  45. }

5、新建GlobalExceptionHandler

新建handler目录，新增：GlobalExceptionHandler.java （全局异常配置）

  1. package com.qingfeng.handler;
  3. import org.springframework.core.Ordered;
  4. import org.springframework.core.annotation.Order;
  5. import org.springframework.web.bind.annotation.RestControllerAdvice;
  7. /**
  8.  * @ProjectName GlobalExceptionHandler
  9.  * @author Administrator
  10.  * @version 1.0.0
  11.  * @Description TODO
  12.  * @createTime 2021/4/19 0019 12:57
  13.  */
  14. @RestControllerAdvice
  15. @Order(value = Ordered.HIGHEST_PRECEDENCE)
  16. public class GlobalExceptionHandler extends BaseExceptionHandler {
  17. }

6、新建HelloController

新建controller目录，新增HelloController.java 测试。

  1. package com.qingfeng.controller;
  3. import lombok.extern.slf4j.Slf4j;
  4. import org.springframework.security.access.prepost.PreAuthorize;
  5. import org.springframework.web.bind.annotation.GetMapping;
  6. import org.springframework.web.bind.annotation.RestController;
  8. import java.security.Principal;
  10. /**
  11.  * @ProjectName TestController
  12.  * @author qingfeng
  13.  * @version 1.0.0
  14.  * @Description TODO
  15.  * @createTime 2021/4/3 0003 20:29
  16.  */
  17. @Slf4j
  18. @RestController
  19. public class HelloController {
  21.     /**
  22.      * @title index
  23.      * @description 首页
  24.      * @author Administrator
  25.      * @updateTime 2021/4/19 0019 13:00
  26.      */
  27.     @GetMapping("index")
  28.     public String hello(String name){
  29.         log.info("青锋欢迎您！！！");
  30.         System.out.println("青锋hello模块");
  31.         return "青锋欢迎您！！！";
  32.     }
  34.     /**

  41.     @PreAuthorize("hasAnyAuthority('user:add')")
  42.     public String userAdd(){
  43.         return "拥有'user:add'权限";
  44.     }
  46.     /**
  47.      * @title user
  48.      * @description 获取当前登录用户
  49.      * @author Administrator
  50.      * @updateTime 2021/4/19 0019 13:00
  51.      */
  52.     @GetMapping("user")
