170705、springboot编程之自定义properties

spring boot使用application.properties默认了很多配置。但需要自己添加一些配置的时候，可以这样用，如下！

在application.properties文件中增加信息

1、在application.properties配置文件增加

##自定义属性
rick.name=rick
rick.age=30

2、自定义配置类RickProperties

package com.rick.common.properties;


import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.stereotype.Component;

@Component
@ConfigurationProperties(prefix = "rick")
public class RickProperties {

    private String name;
    private int age;

    public String getName() {
        return name;
    }

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

    public int getAge() {
        return age;
    }

    public void setAge(int age) {
        this.age = age;
    }
}

3、编写PropertiesController类

package com.rick.apps.controller;

import com.rick.common.ResultJson;
import com.rick.common.properties.RickProperties;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class PropertiesController {

    @Autowired
    private RickProperties rickProperties;


    @GetMapping(value = "/rick")
    public ResultJson rick(){
        System.out.println("name===" + rickProperties.getName());
        System.out.println("age====" + rickProperties.getAge());
        return ResultJson.buildSuccessInstance();
    }

}

4、在主函数增加扫描注解@EnableConfigurationProperties

启动项目，访问http://localhost:8080/rick，查看是否输出内容

在自定义的properties文件中增加信息

1、在resources下新增anna.properties文件

##自定义属性
anna.name=anna
anna.age=20

2、创建AnnaProperties文件

package com.rick.common.properties;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.PropertySource;
import org.springframework.stereotype.Component;

@Component
@Configuration
@PropertySource("classpath:anna.properties")
@ConfigurationProperties(prefix = "anna")
public class AnnaProperties {
    private String address;
    private String gender;

    public String getAddress() {
        return address;
    }

    public void setAddress(String address) {
        this.address = address;
    }

    public String getGender() {
        return gender;
    }

    public void setGender(String gender) {
        this.gender = gender;
    }
}

3、编写PropertiesController类

package com.rick.apps.controller;

import com.rick.common.ResultJson;
import com.rick.common.properties.AnnaProperties;
import com.rick.common.properties.RickProperties;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class PropertiesController {

    @Autowired
    private RickProperties rickProperties;

    @Autowired
    private AnnaProperties annaPropertes;

    @GetMapping(value = "/rick")
    public ResultJson rick() {
        System.out.println("rick.name===" + rickProperties.getName());
        System.out.println("rick.age====" + rickProperties.getAge());
        return ResultJson.buildSuccessInstance();
    }

    @GetMapping(value = "/anna")
    public ResultJson anna() {
        System.out.println("rick.name===" + rickProperties.getName());
        System.out.println("rick.age====" + rickProperties.getAge());
        System.out.println("anna.address===" + annaPropertes.getAddress());
        System.out.println("anna.gender====" + annaPropertes.getGender());
        return ResultJson.buildSuccessInstance();
    }

}

4、启动服务访问http://localhost:8080/anna

注：不同版本的springboot，加载配置文件可能有些不同！
