springboot的findOne方法没有合适的参数使用
开发SpringBoot的DAO层之后，去测试的时候，发现findOne()这个方法找不到了，查看了对应的表字段名和实体类的属性都一致
找了半天没找到是什么原因
最后发现是依赖的版本出问题了
<parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>2.0.0.RELEASE</version> <relativePath/> <!-- lookup parent from repository --> </parent>
这里改为1.5.10之后
就可以正常引入了
<parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>1.5.10.RELEASE</version> <relativePath/> <!-- lookup parent from repository --> </parent>
记录一下，花了3个小时找这个问题。。
SpringBoot踩过的坑之findOne()
因为参考学习的视频还是一点几版本的，所以面对这个问题很无奈
简而言之
findOne()方法的返回值压根就是就不是我想要的User类型
只能换成findById()的方法，但它的返回值是Optional
经过多次百度，我发现这么写可以解决它：
...
@RequestMapping("/getUser")
public User getUser(Integer id) {
Optional<User> user = userDao.findById(id);
System.out.println(user.toString());
if(user.isPresent()){
System.out.println("成功查找到了数据！！！");
return user.get();
}else{
return null;
}
}
...
但是！！！
如果你在实体类中，表名与字段名没有对应的话
就会一直报错――
