在Spring中存储键/值域参数的最佳方法

public class CustomPropertySource extends PropertySource<String> {
    private Map<String, Object> properties;

    public CustomPropertySource() {
        super("customPropertySource");
        // 初始化配置参数
        properties = new HashMap<>();
        properties.put("key1", "value1");
        properties.put("key2", "value2");
    }

    @Override
    public Object getProperty(String name) {
        return properties.get(name);
    }
}

<bean class="org.springframework.context.support.PropertySourcesPlaceholderConfigurer">
    <property name="propertySources">
        <util:list>
            <bean class="com.example.CustomPropertySource" />
        </util:list>
    </property>
</bean>

@Autowired
private Environment environment;

public void someMethod() {
    String value1 = environment.getProperty("key1");
    String value2 = environment.getProperty("key2");
    // 使用配置参数的值进行业务逻辑处理
}
