从jar包中加载feignClient

问题

有些公共的组件抽出来其余模块的maven依赖，此时要在使用的项目中加载此jar包的spring component以及feign组件，仅仅依靠@ComponentScan是不够的，还须要在@EnableFeignClients(basePackages = {"com.xixicat"})中标注basekPackages。

对于maven编译

若是在parent中配置了

<build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
                <executions>
                    <execution>
                        <goals>
                            <goal>repackage</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>
        </plugins>
    </build>

那么若是组件没有main class的话，这里的repackage过不去，则须要在组件的maven中skip掉

<build>
        <plugins>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-compiler-plugin</artifactId>
                <configuration>
                    <source>1.8</source>
                    <target>1.8</target>
                </configuration>
            </plugin>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
                <configuration>
                    <skip>true</skip>
                </configuration>
            </plugin>
        </plugins>
    </build>
