springboot中各模块间实现bean之间互相调用（service以及自定义的bean）

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：

        
            com.example
            demo1
            0.0.1-SNAPSHOT
        

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;

@RestController
public 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;

@Configuration
public 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。
