SpringBoot读取properties中的属性值

1.在application.properties中添加以下内容:

learn.blog.name=hello
learn.blog.title=千回教育系统

2.新增属性关联的类:

package com.czhappy.learn.BootLearn.config;

import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Component;

@Component
public class BlogProperties {

    @Value("${learn.blog.name}")
    private String name;

    @Value("${learn.blog.title}")
    private String title;

    public String getName() {
        return name;
    }

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

    public String getTitle() {
        return title;
    }

    public void setTitle(String title) {
        this.title = title;
    }
}

3.编写controller:

package com.czhappy.learn.BootLearn.controller;

import com.czhappy.learn.BootLearn.config.BlogProperties;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class IndexController {
    @Autowired
    private BlogProperties blogProperties;

    @RequestMapping("/")
    String index() {
        System.out.println(blogProperties.getTitle());
        return blogProperties.getName()+"——"+blogProperties.getTitle();
    }
}

4.启动应用,在浏览器中调用:

注意事项:

如果浏览器中显示中文乱码,需要修改idea的配置:

然后复制application.properties文件中的内容并保存到一个临时文本中,把application.properties文件删除,在原目录重新新建一个application.properties,把临时文本中的内容copy到新建的application.properties文件中,启动项目,即可正确获取中文内容。
