Startup Failed

Symptoms

During the deployment of the Spring Boot startup command in the action Start/Stop Spring Boot, the error message The SpringBoot service startup failed is displayed.

Cause Analysis

The possible causes are as follows:

  • The port is occupied.
  • JDK is not installed or environment variables are incorrectly configured.
  • The value of a parameter is improper or the parameter is incorrectly used.
  • The entered absolute path is incorrect.

Solution

Perform the following steps to rectify the fault:

  1. Run the following command to check whether the port is occupied. If the port is occupied, change the port number and perform the deployment again.
    • Linux 
      lsof -i:8080
netstat -anp|grep 8080
    • Windows 
      netstat -ano|findstr "8080"
  1. Run the following command to check the Java environment. If JDK is not installed, install it through the action Install JDK.
    • Linux 
      java -version
which java
    • Windows 
      java -version
Scenario 1: If the Linux OS is in use and JDK is manually installed, add the JDK environment variables to the following files because the current startup operation is no_login:
  • Ubuntu: ~/.bashrc and ~/.profile
  • Centos: ~/.bashrc and ~/.bash_profile

    The following is a configuration example of the environment variables:

    • export JAVA_HOME=/usr/local/jdk/jdk1.8.0_151
    • export CLASS_PATH=$JAVA_HOME/lib:$JAVA_HOME/jre/lib
    • export PATH=$JAVA_HOME/bin:$PATH
Scenario 2: If the Linux OS is in use and JDK of the version openjdk-1.8.0 is installed using the action Install JDK, you do not need to manually configure JDK. However, you must delete the JDK environment variables from the following files:
  • Ubuntu: ~/.bashrc and ~/.profile
  • Centos: ~/.bashrc and ~/.bash_profile
  1. Set Java running parameters properly, and enter correct command line parameters in the corresponding text boxes. For details about the differences between system variables and command line parameters, see Start/Stop Spring Boot.
  2. Check whether the entered path is correct. If not, modify it and perform the deployment again.
  3. In the action Select Deployment Source, select a JAR file to download.
  4. If the problem persists, check the service startup logs and locate the fault based on the logs.
