Spring ComparisonPropertySource

• Author: HuiFer

• 源码阅读仓库: SourceHot-spring

• 整体代码如下.

  • 下面几个调用方法会直接抛出异常
    1. getSource
    2. containsProperty
    3. getProperty

    static class ComparisonPropertySource extends StubPropertySource {
        // 异常信息
        private static final String USAGE_ERROR =
                "ComparisonPropertySource instances are for use with collection comparison only";
        public ComparisonPropertySource(String name) {
            super(name);
        }
        @Override
        public Object getSource() {
            // 抛异常
            throw new UnsupportedOperationException(USAGE_ERROR);
        }
        @Override
        public boolean containsProperty(String name) {
            // 抛异常
            throw new UnsupportedOperationException(USAGE_ERROR);
        }
        @Override
        @Nullable
        public String getProperty(String name) {
            // 抛异常
            throw new UnsupportedOperationException(USAGE_ERROR);
        }
    }
