1.建一个项目，两个module(注意项目和module都是创建类型如下图)
2、新建module1: demo1 ; module2: demo3，实现demo3 调用 demo1 的service
建好如图：
3.在demo3中引入demo1的依赖，demo3的pom文件中加入：
4.demo1中新建service，实现调用。
package com.example.demo1.controller;import com.example.demo1.configure.TesttConfigure;import com.example.demo1.service.TestService;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.web.bind.annotation.GetMapping;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.RestController;@RestController@RequestMapping("/demo1")public class TestController { @Autowired private TestService testService; @Autowired private TesttConfigure testtConfigure; @GetMapping("/test1") public String test1(){ System.out.println(testtConfigure.ttt()); return testtConfigure.ttt()+testService.testService(); }}
5.demo1中成功调用后，demo3中直接引入依赖就可以
package com.example.demo3.controller;import com.example.demo1.configure.TesttConfigure;import com.example.demo1.service.TestService;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.RestController;@RestControllerpublic class Test3Controller { @Autowired private TestService testService; @Autowired private TesttConfigure testtConfigure; @RequestMapping("/test3") public String test3(){ String str = testService.testService()+"------test3-------"+testtConfigure.ttt(); return str; }}
6.demo3实现调用demo1中自定义的bean。
demo1中自定义bean，启动类中配置，实现能正常能访问
自定义配置类：
package com.example.demo1.configure;import org.springframework.context.annotation.Bean;import org.springframework.context.annotation.Configuration;@Configurationpublic class TesttConfigure { @Bean(name = "Test1") public String ttt(){ return "----tttttt-----"; }}
demo1中启动类设置：
package com.example.demo1;import org.springframework.boot.SpringApplication;import org.springframework.boot.autoconfigure.SpringBootApplication;import org.springframework.context.annotation.ComponentScan;@SpringBootApplication@ComponentScan(basePackages = "com.example.demo1")public class Demo1Application { public static void main(String[] args) { SpringApplication.run(Demo1Application.class, args); }}
controller层注入，实现调用：
package com.example.demo1.controller;import com.example.demo1.configure.TesttConfigure;import com.example.demo1.service.TestService;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.web.bind.annotation.GetMapping;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.RestController;@RestController@RequestMapping("/demo1")public class TestController { @Autowired private TestService testService; @Autowired private TesttConfigure testtConfigure; @GetMapping("/test1") public String test1(){ System.out.println(testtConfigure.ttt()); return testtConfigure.ttt()+testService.testService(); }}
这里的 testtConfigure 是自定义配置类。
demo1能访问成功后，demo3直接注入就可以，和上面注入demo1的service一样。
