【问题描述】：

我使用 FIQL 查询使用 Apache CXF 3.0.0-milestone1 构建的 Web 服务。当我尝试引用 java.util.Calendar 类型的任何属性时，我得到一个 org.apache.cxf.jaxrs.ext.search.PropertyNotFoundException。我已经追踪到 FiqlParser.parse(String expression) 调用的行为，我可以使用下面的简单代码重现它。

搜索豆：导入 java.util.Calendar；导入 java.util.Date;

public class Book {
    private Long id;
    private String title;
    private Date published;
    private Calendar created;

    public Book() {
    }

    public Long getId() {
        return id;
    }

    public void setId(Long id) {
        this.id = id;
    }

    public String getTitle() {
        return title;
    }

    public void setTitle(String title) {
        this.title = title;
    }

    public Date getPublished() {
        return published;
    }

    public void setPublished(Date published) {
        this.published = published;
    }

    public Calendar getCreated() {
        return created;
    }

    public void setCreated(Calendar created) {
        this.created = created;
    }
}

可执行类：

import org.apache.cxf.jaxrs.ext.search.SearchCondition;
import org.apache.cxf.jaxrs.ext.search.fiql.FiqlParser;

public class PlayGround {

    public static void  main(String[] args) {
        FiqlParser<Book> parser = new FiqlParser(Book.class);
        SearchCondition<Book> condition1 = parser.parse("id=ge=0");
        SearchCondition<Book> condition2 = parser.parse("title==*wind*");
        SearchCondition<Book> condition3 = parser.parse("published=ge=2014-01-01");
        SearchCondition<Book> condition4 = parser.parse("created=ge=2013-01-01");
    }
}

PlayGround 在以下行失败：

SearchCondition<Book> condition4 = parser.parse("created=ge=2013-01-01");

堆栈跟踪：

【解决方案1】：

如果您在方法 org.apache.cxf.jaxrs.ext.search.fiql.FiqlParser.parseType(String, String, String) 的 catch 块中放置断点，您将看到此异常消息：

org.apache.cxf.jaxrs.ext.search.SearchParseException: Cannot convert String value "2013-01-01" to a value of class java.util.Calendar
