Spring Boot 读取 properties 文件属性

JeeStudy

Spring Boot 一贯秉承 默认配置，尽量让开发者尽量不配置或少配置。（为什么这么简单呢？）
方法1：

用注解@Value读取配置文件的属性内容


        @Value("${website.author}")
        private String websiteAuthor;
        @Value("${website.name}")
        private String websiteName;

        @Value("${website.author}")
        private String websiteAuthor;
        @Value("${website.name}")
        private String websiteName;

方法2：使用 @ConfigurationProperties 基于类型安全的properties配置

@ConfigurationProperties(prefix = "website")
public class WebSite {
        private String author;
        private String name;

        public String getAuthor() {
                return author;
        }

        public void setAuthor(String author) {
                this.author = author;
        }

        public String getName() {
                return name;
        }

        public void setName(String name) {
                this.name = name;
        }

}

不错，这样绑定真省事
