I've based my code on this post and got a problem compiling my generated class in runtime. When running in the IDE compilation works just fine but when runing from a spring-boot jar compilation fails saying symbols are missing or some package does not exist.

问题 I have a working standalone JAR maven/spring boot app. It currently has its applicationContext.xml and application.properties files in the JAR within /src/main/resources/. For the sake of easily being able to reconfigure without redeploying, I would like to move the .xml file and the .properties file outside of the jar. I've setup the maven-antrun-plugin so it copies those resources into the target directory. However, I'm having difficulty getting these two files (.xml and .properties)

问题 I just updated spring boot from 1.3.2 to 1.4 and as a result also updated jackson from 2.6.5 to 2.8.1. With no other change in code jackson now tries to create instances of my model class using an all-args-constructor (AnnotatedConstructor.java:124) instead of the normal no-args-constructor (AnnotatedConstructor.java:120). Since jackson is using the constructor in the wrong order (setting a String for a Long) this results in an exception: Caused by: com.fasterxml.jackson.databind

问题 I am trying my hands on spring-data-r2dbc. I am try this on Postgresql. I have tried spring-data-mongodb-reactive before. I couldn't help but to compare both.

Ca anyone share any code samples with respect to this. I understand that the underlying database should support this. I believe Postgresql does support this

问题 I have downloaded the Spring cloud Dataflow server code from GitHub at https://github.com/spring-cloud/spring-cloud-dataflow. I am trying to understand how the docker image is build for this server. But I am unable to find dockerfile in this codebase. Reference documentation section "Adding a Custom JDBC Driver" calls for modifying Pom.xml and rebuild with very little information. I need to use a custom jar and rebuild the image. Already looked into this post https://github.com/spring-cloud
