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。
