Spring boot 的 properties 屬性值配置 application.properties 與 自訂properties

標籤：cat   配置   編碼   @Value   com   private   enc   one   utf-8   

1. 配置屬性值
   application.properties 檔案直接配置：
   

   com.ieen.super.name="MDD"

   自訂properties檔案配置：src/main/resources/conf/boot.properties

   com.ieen.boot.name="123"com.ieen.boot.value="456"

2. 調用方法
   @Value 註解調用application.properties屬性值:
   

   @Value("${com.ieen.super.name}")private String name;

   @Value註解調用自訂properties屬性值:

   @PropertySource("classpath:conf/boot.properties")public class Main{    @Value("${com.ieen.boot.name}")    private String bootName;}

   註：@PropertySource 註解引入自訂properties從1.5以後才開始的
   

   // value 為自訂配置// ignoreResourceNotFound 預設false，檔案不存在報錯// encoding 設定編碼// name 為Resource對象的beanname@PropertySource(value = { "classpath:boot.properties",        "classpath:conf/boot.properties" }, ignoreResourceNotFound = false, encoding = "UTF-8", name = "boot-custom.properties")

   @ConfigurationProperties 配置properties屬性對象：

   // spring boot 1.5以前的配置//@ConfigurationProperties(prefix = "com.ieen.boot",locations = "classpath:conf/boot.properties")@ConfigurationProperties(prefix = "com.ieen.boot")
   // 若是自訂properties則加上@PropertySource(value = "classpath:conf/boot.properties", encoding = "UTF-8")@Componentpublic class BootPropertiesBean {    private String name;    private String value;    public String getName() {        return name;    }    public void setName(String name) {        this.name = name;    }    public String getValue() {        return value;    }    public void setValue(String value) {        this.value = value;    }}

       @Autowired    private BootPropertiesBean bean;
