This article shows you the problems encountered in the springboot project connecting to sap and deploying to docker. The content is concise and easy to understand, which will definitely brighten your eyes. I hope you can get something through the detailed introduction of this article.

Preface

Mainly record the problems encountered in assisting the deployment of access to sap, and only record the answers to the problems, without explaining the principle.

Question 1, question 1: Illegal JCo archive "sapjco-1.0.jar". It is not allowed to rename or repackage the original archive "sapjco3.jar"

Solution 1: rename sapjco-1.0.jar to sapjco3.jar in a manual project

But we didn't adopt this plan.

Solution 2: specify the scope of maven as system, as follows

Com.sap sapjco ${sap.version} system ${project.basedir} / lib/sapjco3.jar

Then specify resources, which looks like this

Org.springframework.boot spring-boot-maven-plugin ${spring-boot.version} repackage Maven-compiler-plugin 1.81.8 UTF-8 ${project.basedir} / lib ${project.basedir} / lib BOOT-INF/lib/ * * / .jar ${project.basedir} / lib BOOT-INF * * / * .so * * / * .dll src/main/resources * * / * .yml * * / .xml

The function of this is to push sapjco3.jar into BOOT-INF/lib/.

Question 2: java.lang.UnsatisfiedLinkError: no sapjco3 in java.library.path

Because the project is deployed to docker, this article only writes about docker-based solutions.

Solutions are as follows:

Specify the LD_LIBRARY_PATH environment variable in dockerFile, which looks like this

FROM adoptopenjdk/openjdk8VOLUME / tmp#ENV JAVA_OPTS= "- Dcom.sun.management.jmxremote.port=39083-Dcom.sun.management.jmxremote.ssl=false-Dcom.sun.management.jmxremote.authenticate=false" ENV JAVA_OPTS= "ENV LD_LIBRARY_PATH / usr/local/lib:$LD_LIBRARY_PATHCOPY localtime / etc/localtimeRUN echo" Asia/Shanghai "> / etc/timezoneCOPY hello-biz/target/hello-biz-*.jar app.jarCOPY hello-biz/lib/libsapjco3.so / usr/local/lib/libsapjco3.soENTRYPOINT [" sh ","-c " "java $JAVA_OPTS-Djava.security.egd=file:/dev/./urandom-jar / app.jar"] these are the problems encountered by the springboot project in connecting to sap and deploying to docker.
