概述
1、maven pom配置如下文件：
org.springframework.boot
spring-boot-starter-parent
2.1.6.RELEASE
2、自定实现一个自己的域存储库：
package com.springdata.jpa01.repository;
import com.springdata.jpa01.entity.User;
public interface MyUserRepository extends MyBaseRepository<User, Long> {
public User findById(Long id);
}
package com.springdata.jpa01.repository;
import com.springdata.jpa01.entity.User;
public interface MyUserRepository extends MyBaseRepository<User, Long> {
public User findById(Long id);
}
自定义存储库的好处，个人认为在于可以自定义暴露想要的方法
报错：
Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name ‘myUserRepository’: Invocation of init method failed; nested exception is java.lang.IllegalArgumentException: Failed to create query for method public abstract java.lang.Object com.springdata.jpa01.repository.MyBaseRepository.findById1(java.io.Serializable)!

错误原因在于之前的方法名定义错误，后来findById正确，个人感觉真正的原因为SpringData Jpa底层利用动态代理的方法实现的，我动态代理比如jdk原生支持的目标类（SimpleJpaRepository）和代理类实现同一个接口,如果我们方法名定义错误将无法与目标类进行匹配，这是一个约定的规则，所以会包上面错误。
