springboot项目读取自定义porperties文件

1.1.定义简单.properties文件

datasource.dataSources[0].id=1
datasource.dataSources[0].dsId=postgisA
datasource.dataSources[0].type=postgis
datasource.dataSources[0].driver=org.postgresql.Driver
datasource.dataSources[0].url=jdbc:postgresql://
datasource.dataSources[0].user=postgres
datasource.dataSources[0].pwd=****

1.2.定义实体类

import lombok.Data;

@Data
public class DataSource {
    private int id;
    private String dsId;
    private String type;
    private String driver;
    private String url;
    private String user;
    private String pwd;
}

1.3.读取配置文件

import lombok.Data;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.PropertySource;

import java.util.ArrayList;

@Data
@Configuration
@PropertySource("classpath:property/datasource.properties")
@ConfigurationProperties(prefix = "datasource")
public class DataSources {
    private ArrayList<DataSource> dataSources;
}

2.1定义复杂.properties

services.servers[0].name=Test
services.servers[0].dsId=postgisA
services.servers[0].layers[0].name=Test
services.servers[0].layers[0].type=LineString
services.servers[0].layers[0].minLevel = 16
services.servers[0].layers[0].maxLevel = 18
services.servers[0].layers[1].name=Test2
services.servers[0].layers[1].type=Point
services.servers[0].layers[1].minLevel = 16
services.servers[0].layers[1].maxLevel = 18

2.2定义两个实体类

import lombok.Data;

@Data
public class Layer {
   
    private String name;
   
    private String type;
    
    private int minLevel;
   
    private int maxLevel;
}

import lombok.Data;

import java.util.ArrayList;
@Data
public class LayerService {
    private int id;
    private String name;
    private String dsId;
    private String extent;
    private String cachePath;
    private ArrayList<Layer> layers;
}

2.3读取配置

import lombok.Data;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.PropertySource;

import java.util.ArrayList;

@Data
@Configuration
@PropertySource("classpath:property/services.properties")
@ConfigurationProperties(prefix = "services")
public class Services {
    private ArrayList<LayerService> servers;
}

3.使用

直接注入

@Autowired
DataSources dataSources;
@Autowired
Services services;
