将spring boot stater parent 1.5.9 RELEASE更改为2.0.1 RELEASE

时出现以下错误

目标/万无一失的报告

我的配置中是否需要更改才能使其正常工作？

application.properties

spring.datasource.url=jdbc:mysql://localhost:3306/boot_rest_api
spring.datasource.username=root
spring.datasource.password=root
spring.datasource.driver-class-name=com.mysql.jdbc.Driver

## Hibernate Properties
# The SQL dialect makes Hibernate generate better SQL for the chosen database
#spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.MySQL5Dialect
spring.jpa.database-platform=org.hibernate.dialect.MySQL5InnoDBDialect


# Hibernate ddl auto (create, create-drop, validate, update)
# spring.jpa.hibernate.ddl-auto = update
spring.jpa.hibernate.ddl-auto=create


logging.level.root=DEBUG

申请主

@SpringBootApplication
@EnableJpaRepositories("com.restapispringboot.repo")
@EntityScan("com.restapispringboot.model")
public class RestApiSpringbootApplication {

    public static void main(String[] args) {
        SpringApplication.run(RestApiSpringbootApplication.class, args);
    }
}

实体

@Entity
@Table(name = "customer")
public class Customer implements Serializable {
   // getters and setters
}

回购

public interface CustomerRepository extends CrudRepository<Customer, Long> {
    List<Customer> findByLastName(String lastName);

}

更新我只是注意到mvn clean install时我也遇到以下错误。但我检查了我的构建路径，JRE [JavaSE-1.8]和maven依赖项都是构建路径......

ERROR] error reading /Users/erichuang/.m2/repository/org/aspectj/aspectjweaver/1.8.13/aspectjweaver-1.8.13.jar; invalid CEN header (bad signature)

正如评论中所述，您的错误是java.lang.NoClassDefFoundError: javassist/bytecode/ClassFile。

当您从春季启动版本1.5.9 RELEASE迁移到2.0.1 RELEASE时，javassist jar (3.20.0-GA vs 3.22.0-GA)可能存在一些冲突。

所以你可以清理你的maven repo（删除localRepository）并再次运行你的命令。
