诡异的情况..JSON.toString 时，复杂嵌套对象里 List为空。。

[BlankRain]

预期与结果不一致.

fastjson 的结果: {"data":[{},{},{},{},{}],"head":["姓名","类型","状态","满意度","统计","时间"],"size":5}

预期的结果: {"data":[{"姓名":"A0","时间":"F0","满意度":"D0","状态":"C0","类型":"B0","统计":"E0"},{"姓名":"A1","时间":"F1","满意度":"D1","状态":"C1","类型":"B1","统计":"E1"},{"姓名":"A2","时间":"F2","满意度":"D2","状态":"C2","类型":"B2","统计":"E2"},{"姓名":"A3","时间":"F3","满意度":"D3","状态":"C3","类型":"B3","统计":"E3"},{"姓名":"A4","时间":"F4","满意度":"D4","状态":"C4","类型":"B4","统计":"E4"}],"head":["姓名","类型","状态","满意度","统计","时间"],"size":5}

直接贴代码，代码不复杂，三个类文件

建maven工程,用到的Maven依赖

        System.out.println(demoResult.fastJSONStr());
        System.out.println(demoResult.netsfJSONStr());

        for (int i = 0; i < 5; i++) {
            app.demo.ClassRoom.People a1 = new app.demo.ClassRoom.People();
            a1.set姓名("A" + i);
            a1.set类型("B" + i);
            a1.set状态("C" + i);
            a1.set满意度("D" + i);
            a1.set统计("E" + i);
            a1.set时间("F" + i);
            list.add(a1);
        }
        return list;
    }
}

Main.java 运行结果:

{"data":[{},{},{},{},{}],"head":["姓名","类型","状态","满意度","统计","时间"],"size":5}

{"data":[{"姓名":"A0","时间":"F0","满意度":"D0","状态":"C0","类型":"B0","统计":"E0"},{"姓名":"A1","时间":"F1","满意度":"D1","状态":"C1","类型":"B1","统计":"E1"},{"姓名":"A2","时间":"F2","满意度":"D2","状态":"C2","类型":"B2","统计":"E2"},{"姓名":"A3","时间":"F3","满意度":"D3","状态":"C3","类型":"B3","统计":"E3"},{"姓名":"A4","时间":"F4","满意度":"D4","状态":"C4","类型":"B4","统计":"E4"}],"head":["姓名","类型","状态","满意度","统计","时间"],"size":5}

中文方法名，你强！可以使用@JSONField(name="类型")

[wenshao]

已经修复，请等待1.2.8版本发布

哈哈哈,中文方法咋了? utf8 问题不大吧。。
其实,我一直期待一门汉语风格的编程语言...不是vb翻版出来的易语言那种...
