使用启动我的应用程序时,一切工作正常Intellij
。但是当我fatJar
使用gradle plugin:创建eu.appsatori.fatjar
并执行时:
java -jar myapp.jar
我得到这样的东西:
11:41:01.224 [main] ERROR org.springframework.boot.SpringApplication - Application startup failed
org.springframework.beans.factory.BeanDefinitionStoreException: Failed to process import candidates for configuration class [my.testing.MyAppMain]; nested exception is java.lang.IllegalArgumentException: No auto configuration classes found in META-INF/spring.factories. If you are using a custom packaging, make sure that file is correct.
at org.springframework.context.annotation.ConfigurationClassParser.processDeferredImportSelectors(ConfigurationClassParser.java:482)
at org.springframework.context.annotation.ConfigurationClassParser.parse(ConfigurationClassParser.java:184)
...
似乎在中找不到自动配置类META-INF/spring.factories
。
如何添加此文件?内容应该是什么?
我有以下构建脚本:
apply plugin: "java";
apply plugin: "idea";
apply plugin: 'application'
apply plugin: 'eu.appsatori.fatjar'
apply plugin: 'org.springframework.boot'
repositories {
mavenCentral()
}
buildscript {
ext {
springBootVersion = '1.4.3.RELEASE'
}
repositories {
mavenCentral()
jcenter()
}
dependencies {
classpath "org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}"
classpath "eu.appsatori:gradle-fatjar-plugin:0.3"
}
}
sourceSets {
main {
java {
srcDir 'src/main/java'
}
resources {
srcDir 'src/main/resources'
}
}
test {
java {
srcDir 'src/test/java'
}
}
}
fatJar {
manifest {
attributes("Main-Class": 'my.testing.MyAppMain')
}
exclude 'META-INF/*.DSA'
exclude 'META-INF/*.SF'
exclude 'META-INF/*.RSA'
}
dependencies {
compile 'org.springframework.boot:spring-boot-starter-jdbc'
runtime 'mysql:mysql-connector-java'
testCompile 'org.springframework.boot:spring-boot-starter-test'
}
我的示例代码是:
package my.testing;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.ConfigurableApplicationContext;
import org.springframework.jdbc.core.JdbcTemplate;
import org.springframework.stereotype.Component;
@SpringBootApplication
public class MyAppMain {
private ConfigurableApplicationContext springContext;
@Autowired
private SimpleDao dao;
public static void main(String[] args) throws Exception {
MyAppMain test = new MyAppMain();
try {
test.init();
test.doWhatYouGotToDo();
} finally {
test.stop();
}
}
private void doWhatYouGotToDo() {
System.out.println("Auto-wired dao: " + dao.hashCode());
System.out.println("Auto-wired jdbcTemplate: " + dao.jdbcTemplate.hashCode());
}
private void init() throws Exception {
springContext = SpringApplication.run(MyAppMain.class);
springContext.getAutowireCapableBeanFactory().autowireBean(this);
}
private void stop() throws Exception {
springContext.close();
}
}
@Component
class SimpleDao {
@Autowired
JdbcTemplate jdbcTemplate;
}
application.properties
文件:
spring.datasource.driver-class-name = com.mysql.jdbc.Driver
spring.datasource.url = jdbc:mysql://localhost:3306/some_db?useSSL=false&serverTimezone=UTC
spring.datasource.username = some_user
spring.datasource.password = some_pass
注意:这个问题是基于SpringBoot制作的jar文件-在META-INF / spring.factories中找不到所有自动配置类,那里的所有答案都指的是with的构建Maven
。请仅在Gradle
此处输入与之相关的答案。
