在IBM MobileFirst 8.0中使用带有Java适配器的外部库是否有任何限制?
当我添加guava时,我的代码没有错误(mfpdev适配器构建成功),但在部署到我的服务器时,它会响应错误:
\n
但是当我在pom(mvn依赖项)中删除guava时,我能够部署适配器。我可以看到的问题也发生在其他一些库中。有没有选择使用这样的库?
mfpdev -v:8.0.0-2017012016
编辑:我最终通过在pom文件中设置guava的范围来解决问题:
$n
答案 0 :(得分:0)
我在MFP 8.0环境中试过这个,但没有看到问题。
mfpdev -v
8.0.0-2017012016
0. Create a sample Java adapter "mfpdev adapter create"
1. Added dependency with guava 21 in pom.xml
<dependency>
<groupId>com.google.guava</groupId>
<artifactId>guava</artifactId>
<version>21.0</version>
</dependency>
2. added a simple guava package and used it.
import com.google.common.base.Optional;
@GET
@Produces(MediaType.TEXT_PLAIN)
public String getResourceData() {
// log message to server log
logger.info("Logging info message...");
Integer invalidInput = new Integer(20);
Optional<Integer> a = Optional.of(Input);
Optional<Integer> b = Optional.of(new Integer(10));
logger.info("Logging my message with guava");
);
return "Hello from guava resource "+sum(a,b) ;
}
4. build, deploy went successful
5. Access above resource
Request URL
http://localhost:9080/mfp/api/adapters/testGuavaAdapter/resource
Response Body
