從jar包中加載feignClient

問題

有些公共的組件抽出來其餘模塊的maven依賴，此時要在使用的項目中加載此jar包的spring component以及feign組件，僅僅依靠@ComponentScan是不夠的，還須要在@EnableFeignClients(basePackages = {"com.xixicat"})中標註basekPackages。

對於maven編譯

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>

那麼若是組件沒有main class的話，這裏的repackage過不去，則須要在組件的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>
