Can anyone help?Thank you

Answer 1

That would suggest you don't have all you dependencies in you jar. Are you running correct jar - you might have more than one - one with app and one from boot in a different dir. Would be good to see a command you use to build as well.

Answer 2

使用mvn包构建命令，它将构建一个带有依赖项的jar并使用该jar

Answer 3

My jar running well, after i choose to manual config Database connection

add in Application class

@EnableAutoConfiguration(exclude={DataSourceAutoConfiguration.class})

and then create

@Configuration
@PropertySource({ "classpath:app.datasource.properties" })
class DatabaseConfig {
@Autowired
private Environment env;

@Bean
@Primary
public DataSource dataSource() {
    DriverManagerDataSource dataSource = new DriverManagerDataSource();
    dataSource.setDriverClassName(env.getProperty("app.datasource.driverClassName"));
    dataSource.setUrl(env.getProperty("app.datasource.url"));
    dataSource.setUsername(env.getProperty("app.datasource.username"));
    dataSource.setPassword(env.getProperty("app.datasource.password"));

    return dataSource;
}    

i don't know why my jar can't get autoconfiguration from spring, maybe someone can explain in comments below
