Spring Boot讀取配置檔案與配置檔案優先順序

spring boot讀取配置檔案

package com.ivan.config.controller;

import org.springframework.beans.factory.annotation.autowired;
import org.springframework.core.env.environment;
import org.springframework.web.bind.annotation.requestmethod;
import org.springframework.web.bind.annotation.restcontroller;
@restcontroller
public class configcontroller 
public string getconfigenvironment()
}

package com.ivan.config.entity;

import org.springframework.boot.context.properties.configurationproperties;
import org.springframework.context.annotation.configuration;
import org.springframework.context.annotation.propertysource;
@configuration
@propertysource("classpath:config/druid.properties")
@configurationproperties(prefix = "druid")
public class druidconfig 
public void setinitialsize(int initialsize) 
public int getminidle() 
public void setminidle(int minidle) 
public int getmaxactive() 
public void setmaxactive(int maxactive) 
public int getmaxwait() 
public void setmaxwait(int maxwait) 
public string getvalidationquery() 
public void setvalidationquery(string validationquery) 
public boolean istestwhileidle() 
public void settestwhileidle(boolean testwhileidle) 
public boolean istestonborrow() 
public void settestonborrow(boolean testonborrow) 
public boolean istestonreturn() 
public void settestonreturn(boolean testonreturn) 
@override
public string tostring() 
}

druid.initialsize=5

druid.minidle=5
druid.maxactive=20
druid.maxwait=60000
druid.validationquery=select 'x'
druid.testwhileidle=true 
druid.testonborrow=true 
druid.testonreturn=true

package com.ivan.config.controller;

import org.springframework.beans.factory.annotation.autowired;
import org.springframework.web.bind.annotation.requestmethod;
import org.springframework.web.bind.annotation.restcontroller;
import com.ivan.config.entity.druidconfig;
@restcontroller
public class druidconfigcontroller 
}

1：需要得到配置屬性的類如下，可以在任何需要得到配置的地方用@value註解

package com.ivan.config.entity;

import org.springframework.beans.factory.annotation.value;
import org.springframework.context.annotation.configuration;
@configuration
public class valuetest ")
private string username;
public string getusername() 
public void setusername(string username) 
}

package com.ivan.config.controller;

import org.springframework.beans.factory.annotation.autowired;
import org.springframework.web.bind.annotation.requestmethod;
import org.springframework.web.bind.annotation.restcontroller;
import com.ivan.config.entity.valuetest;
@restcontroller
public class valuecontroller 
}
