引言
在前面的学习中我们学会了使用springboot yaml配置文件。
但是我们发现我们自己配置的和默认的似乎有些不同,就是默认的配置选项他会有提示,通过阅读springboot 官方文档后找到了解决方案。
新建实体类
Person.java
package com.example.bootyaml.entity;
import lombok.Data;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.stereotype.Component;
import java.util.HashMap;
import java.util.List;
import java.util.Set;
@ConfigurationProperties(prefix = "person")
@Component
@Data
public class Person {
private String name;
private Integer age;
private List<String> hobby;
private HashMap<String, Set<String>> techStack;
private Pet pet;
}
Pet.java
package com.example.bootyaml.entity;
import lombok.Data;
@Data
public class Pet {
private String name;
private Double weight;
}
配置yaml提示
我们先看看官方文档怎么说的
You can easily generate your own configuration metadata file from items annotated with
@ConfigurationProperties by using the spring-boot-configuration-processor jar. The jar includes a
Java annotation processor which is invoked as your project is compiled.
This dependency ensures that the additional metadata is available when the annotation processor
runs during compilation.
也就是我们需要spring-boot-configuration-processor
这个依赖他可以确保你在外部配置文件中实现属性提示
添加maven依赖
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-configuration-processor</artifactId>
<optional>true</optional>
</dependency>
然后我们再试试
大功告成
