The question is published on by Tutorial Guruji team.
I try below guild of schedule-task and it worked.
http://spring.io/guides/gs/scheduling-tasks/
next, I want to access web-api from @Scheduled annotated method, and add below dependency to my build.gradle, to use RestTemplate.
compile 'org.springframework.boot:spring-boot-starter-web:1.2.1.RELEASE'
but, below Exception occurs.
Exception in thread "main" org.springframework.context.ApplicationContextException: Unable to start embedded container; nested exception is org.springframework.context.ApplicationContextException: Unable to start EmbeddedWebApplicationContext due to missing EmbeddedServletContainerFactory bean. at org.springframework.boot.context.embedded.EmbeddedWebApplicationContext.onRefresh(EmbeddedWebApplicationContext.java:133) at org.springframework.context.support.AbstractApplicationContext.refresh(AbstractApplicationContext.java:474) at org.springframework.boot.context.embedded.EmbeddedWebApplicationContext.refresh(EmbeddedWebApplicationContext.java:118) at org.springframework.boot.SpringApplication.refresh(SpringApplication.java:691) at org.springframework.boot.SpringApplication.run(SpringApplication.java:321) at org.springframework.boot.SpringApplication.run(SpringApplication.java:961) at org.springframework.boot.SpringApplication.run(SpringApplication.java:950) at my.pkg.Application.main(BatchApplication.java:14)
Caused by: org.springframework.context.ApplicationContextException: Unable to start EmbeddedWebApplicationContext due to missing EmbeddedServletContainerFactory bean. at org.springframework.boot.context.embedded.EmbeddedWebApplicationContext.getEmbeddedServletContainerFactory(EmbeddedWebApplicationContext.java:183) at org.springframework.boot.context.embedded.EmbeddedWebApplicationContext.createEmbeddedServletContainer(EmbeddedWebApplicationContext.java:156) at org.springframework.boot.context.embedded.EmbeddedWebApplicationContext.onRefresh(EmbeddedWebApplicationContext.java:130)
do I need specific setting to use RestTemplate from @Scheduled method ?
my full build.gradle is below, other files are same to guide.
buildscript {
repositories {
mavenLocal()
mavenCentral()
}
dependencies {
classpath 'org.springframework.boot:spring-boot-gradle-plugin:1.2.1.RELEASE'
}
}
apply plugin: 'java'
apply plugin: 'idea'
apply plugin: 'spring-boot'
repositories {
mavenLocal()
mavenCentral()
}
dependencies {
compile 'org.springframework.boot:spring-boot-starter:1.2.1.RELEASE'
// below line I added.
compile 'org.springframework.boot:spring-boot-starter-web:1.2.1.RELEASE'
}
Answer
A dependency on spring-boot-starter-web is intended for web applications that need a servlet container. It’s overkill if all you need is RestTemplate. Replace the dependency with one on org.springframework:spring-web
