解决springboot集成springdataJpa的数据库字段名_问题

在yml中加入如

  jpa:
    database: MYSQL
    show-sql: true
    hibernate:
      ddl-auto: update

     * naming.physical-strategy: org.hibernate.boot.model.naming.PhysicalNamingStrategyStandardImpl 

这样就可以解决了

多对多的表关系

/**
* 用户
*/
@ManyToMany(cascade = CascadeType.ALL,fetch = FetchType.LAZY)
@JoinTable(name = "sys_userrole", 
joinColumns = {@JoinColumn(name = "roleId")}, 
    inverseJoinColumns = {@JoinColumn(name = "userId")}
)
private List<SysUser> users;
