fastjson过滤属性

//实现PropertyFilter中的apply方法

public class ComplexPropertyPreFilter implements PropertyFilter {
	private Map<Class<?>,Set<String>> includeMap = new HashMap<Class<?>,Set<String>>();
	//@Override
	public boolean apply(Object source,String name,Object value) {
		for(Entry<Class<?>,Set<String>> entry : includeMap.entrySet()) {
			Class<?> class1 = entry.getKey();
			if(source.getClass() == class1){
				Set<String> fields = entry.getValue();
				for(String field : fields) {
					if(field.equals(name)){
						return false;
					}
				}
			}
		}
		return true;
	}
	
	public ComplexPropertyPreFilter(Map<Class<?>,Set<String>> includeMap){
		this.includeMap = includeMap;
	}
}

测试类：

class Wheel{
	String name;
	int size;
	String color;

	public String getColor() {
		return color;
	}
	public void setColor(String color) {
		this.color = color;
	}
	public Wheel() {
		super();
		this.color="black";
		this.name="miqilin";
		this.size = 17;
	}
	
	
}
class Sofa{
	String color;
	int count;
	String texture;
	public String getColor() {
		return color;
	}
