无法更改spring属性文件的名称

spring-boot

Sahand · 技术社区 · 7 年前

我有一个名为 应用程序.属性 以下内容:

mysql.connectionUrl=jdbc:somesql://index.mycust.cr:0000/dbName
mysql.username=me
mysql.password=mypass

这是我们班用的 dbnameConnectionProperties.java 这样地:

package com.mycom.mycust.somesql.dbconnection;

@Configuration
@PropertySource("classpath:application.properties")
@ConfigurationProperties("mysql")
public class DbNameConnectionProperties {

    private String connectionUrl;
    private String username;
    private String password;

    public String getConnectionUrl() {
        return connectionUrl;
    }

    public void setConnectionUrl(String connectionUrl) {
        this.connectionUrl = connectionUrl;
    }

    public String getUsername() {
        return username;
    }

    public void setUsername(String username) {
        this.username = username;
    }

    public String getPassword() {
        return password;
    }

    public void setPassword(String password) {
        this.password = password;
    }
}

这很好。现在我想更改 应用程序.属性 文件(对于另一个数据库,我需要另一个包含属性的文件)。所以我只需更改 应用程序.属性 到 某物、财产 ,以及 @PropertySource 注释:

某物、财产 以下内容:

mysql.connectionURL=jdbc:somesql://index.mycust.cr:0000/dbname
mysql.username=我
mysql.password=mypass

dbnameConnectionProperties.java 以下内容:

package com.mycom.mycust.somesql.dbconnection;

@Configuration
@PropertySource("classpath:something.properties")
@ConfigurationProperties("mysql")
public class DbNameConnectionProperties {

    // same as before
}

这个崩溃:

为什么?

看起来像 something.properties 不在类路径上。仔细检查它是在资源目录中创建的。
