Maven 插件启动超时 spring application did not start before the configured timeout 30000ms

问题

今天 mvn 启动应用报错
spring application did not start before the configured timeout 30000ms

苦思良久，肯定是插件启动超时，应该有配置的，但是没找到

最后在 stackoverfllow 上看到大神说

You are trying to start a spring boot app before in pre-integration-test phase. The spring-boot-maven-plugin StartMojo class (org.springframework.boot.maven) is complaining because the app is not started within the default timeout, wich is defined by the attributes "wait" (defautl value: 500 ms) and "maxAttempts" (default: 60) -> 500 * 60.

/**
 * The number of milli-seconds to wait between each attempt to check if the spring
 * application is ready.
 */
@Parameter
private long wait = 500;

/**
 * The maximum number of attempts to check if the spring application is ready.
 * Combined with the "wait" argument, this gives a global timeout value (30 sec by
 * default)
 */
@Parameter
private int maxAttempts = 60;

"wait" and "maxAttempts" are annotated @Parameter, which means you can change their value from within your pom file, in the plugin configuration like this:

<plugin>
     <groupId>org.springframework.boot</groupId>
     <artifactId>spring-boot-maven-plugin</artifactId>
     <configuration>
              <wait>1000</wait>
              <maxAttempts>180</maxAttempts>
     </configuration>
     <executions>
              ...
     </executions> 
</plugin>
