Spring boot 自定义配置实现自动提示

Spring boot 自定义配置实现自动提示

这个是基于IDE来做的，Eclipse的没有试验过

1、新建一个配置类(ExampleProperties)

package org.yujuan.springbootlearning.properties;

import lombok.Data;
import org.springframework.boot.context.properties.ConfigurationProperties;

@Data
@ConfigurationProperties(prefix = "example")
public class ExampleProperties {
    /**姓名**/
    private String name;
    /**路径**/
    private String path;
    /**是否开启*/
    private Boolean enable;
}

2、引入依赖spring-boot-configuration-processor

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd">

        <version>2.1.7.RELEASE</version>
        <relativePath/> <!-- lookup parent from repository -->
    </parent>

            <artifactId>spring-boot-starter</artifactId>
        </dependency>

        <dependency>

            <artifactId>lombok</artifactId>

        </dependency>

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-configuration-processor</artifactId>
            <optional>true</optional>
        </dependency>
    </dependencies>

    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
        </plugins>
    </build>

</project>

3、修改IDE的配置

打开设置页面，按照箭头所指示的地方开启Enable annotation processing

4、重新编译

会在target目录下的META_INF 下生成spring-configuration-metadata.json文件，同时在配置文件写填写配置时，会自动提示。如下图：
