Question

1.配置文件： {代码...} 2.相关代码 {代码...} 3.尝试解决的方案： 1.&lt;util:properties id="propertiesReader" location="classpath:test.properties" /&gt; 2、在类中需要注入的属性实现 setter 和 getter 方...

PHPz · Answer

No need for get set method

@Value("#{propertiesReader}")
public Properties props;

@Value("#{propertiesReader['username']}")
public String username;

PHP中文网 · Answer

Since you want to inject the entire properties, you should write:

@Value("#{propertiesReader}")
public void setProps(Properties props) {
    this.props = props;
}

instead of

@Value("#{propertiesReader[username]}")
