JSON字符串转对象，List集合，需要的jar 包

Maven项目下需要6个jar包，但是经过测试发现有个包无法下载到本地，故从本地导入

1、先写maven 配置jar，此处引入5个jar

<dependency>
    <groupId>commons-beanutils</groupId>
    <artifactId>commons-beanutils</artifactId>
    <version>1.9.3</version>
</dependency>
<dependency>
    <groupId>net.sf.ezmorph</groupId>
    <artifactId>ezmorph</artifactId>
    <version>1.0.6</version>
</dependency>

2、本地导入最重要的jar：

 测试转成对象：

 String arrayStr = "[{\"user\":{\"userId\":null,\"uname\":\"zhangsan\",\"pwd\":null,\"email\":null,\"schoolName\":null,\"teamMember\":null,\"roles\":null,\"enable\":null},\"apply\":{\"applyId\":3,\"applyTime\":\"2020-03-23T15:42:36.000+0000\",\"user\":null},\"report\":{\"reportId\":1,\"filesName\":\"1：温湿度、光照数据实时显示(10分）#The0questionFA1866E0CB314B1B912437EDC55948BF_one.apk; 2：建立数据库(15分）#The1question95E407157C0A4BDEBE21F6CE4E0910F5_two.apk;\",\"score\":null,\"uploadTime\":\"2020-03-20T10:27:10.000+0000\",\"user\":null}},{\"user\":{\"userId\":null,\"uname\":\"wangwu\",\"pwd\":null,\"email\":null,\"schoolName\":null,\"teamMember\":null,\"roles\":null,\"enable\":null},\"apply\":{\"applyId\":4,\"applyTime\":\"2020-03-23T15:46:33.000+0000\",\"user\":null},\"report\":null},{\"user\":{\"userId\":null,\"uname\":\"lqy\",\"pwd\":null,\"email\":null,\"schoolName\":\"理工大学\",\"teamMember\":\"王雅雯；\",\"roles\":null,\"enable\":null},\"apply\":{\"applyId\":5,\"applyTime\":\"2020-03-23T16:36:32.000+0000\",\"user\":null},\"report\":null}]";
//转化为list
List<UserReportApply> list2= JSONArray.toList(JSONArray.fromObject(arrayStr), UserReportApply.class);

for (UserReportApply stu : list2) {
    System.out.println(stu);
}

　　输出结果：

bean.UserReportApply{user=bean.User{userId=null, uname='zhangsan', pwd='null', email='null', schoolName='null', teamMember='null', roles=null, enable=null}, apply=bean.Apply{applyId=3, applyTime=2020-03-23T15:42:36.000+0000, user=null}, report=bean.Report{reportId=1, filesName='1：温湿度、光照数据实时显示(10分）#The0questionFA1866E0CB314B1B912437EDC55948BF_one.apk; 2：建立数据库(15分）#The1question95E407157C0A4BDEBE21F6CE4E0910F5_two.apk;', score=null, uploadTime=2020-03-20T10:27:10.000+0000, user=null}}
bean.UserReportApply{user=bean.User{userId=null, uname='wangwu', pwd='null', email='null', schoolName='null', teamMember='null', roles=null, enable=null}, apply=bean.Apply{applyId=4, applyTime=2020-03-23T15:46:33.000+0000, user=null}, report=null}
bean.UserReportApply{user=bean.User{userId=null, uname='lqy', pwd='null', email='null', schoolName='理工大学', teamMember='王雅雯；', roles=null, enable=null}, apply=bean.Apply{applyId=5, applyTime=2020-03-23T16:36:32.000+0000, user=null}, report=null}

　结果正确！
