Question

我使用以下代码反序列化JSON对象：

Trying to deserialize the following string: { "start_time":"2015-10-19T13:00:00.000+02:00", "interval":900,"unit":"kW","target_values": [50.3253179, 45.15539599955082, 56.13061499595642, 68.14941400289536, 65.17419399321079, 63.140625, 47.14074699580669, 28.16027800738811, 61.14758299291134],"prosumers_primary":[  "Pr_1","Pr_4","Pr_7","Pr_1"],"prosumers_secondary":[  "Pr_2","Pr_3","Pr_8","Pr_11","Pr_16"]}
Done, the resulting object is: com.wattics.vimen.DSSdata.DRRequest@5ae50ce6

当我从测试中调用代码时，它正常工作，我得到以下输出：

Info:   Trying to deserialize the following string: { "start_time":"2015-10-19T13:00:00.000+02:00", "interval":900,"unit":"kW","target_values": [50.3253179, 45.15539599955082, 56.13061499595642, 68.14941400289536, 65.17419399321079, 63.140625, 47.14074699580669, 28.16027800738811, 61.14758299291134],"prosumers_primary":[  "Pr_1","Pr_4","Pr_7","Pr_1"],"prosumers_secondary":[  "Pr_2","Pr_3","Pr_8","Pr_11","Pr_16"]}

但是当我尝试使用servlet中的代码时，我收到以下错误：

package com.wattics.vimen.DSSdata;

import org.joda.time.DateTime;

import com.fasterxml.jackson.annotation.JsonIgnoreProperties;

@JsonIgnoreProperties(ignoreUnknown = true)
public class DRRequest {

  public DateTime start_time;
  public String start_time_text;
  public int interval;
  public String unit;
  public Double[] target_values;
  public String[] prosumers_primary;
  public String[] prosumers_secondary;
  public String type;

}

任何人都可以帮助我了解导致异常的原因，如何修复它？

关联类的代码如下所示：

pom.xml

在文件<dependencies> <dependency> <groupId>javax.servlet</groupId> <artifactId>servlet-api</artifactId> <version>2.5</version> <scope>provided</scope> </dependency> <dependency> <groupId>com.fasterxml.jackson.datatype</groupId> <artifactId>jackson-datatype-joda</artifactId> <version>2.8.1</version> </dependency> <dependency>  <groupId>com.fasterxml.jackson.core</groupId> <artifactId>jackson-annotations</artifactId> <version>2.8.1</version> </dependency> <dependency> <groupId>com.fasterxml.jackson.core</groupId> <artifactId>jackson-core</artifactId> <version>2.8.1</version> </dependency> <dependency> <groupId>ch.qos.logback</groupId> <artifactId>logback-classic</artifactId> <version>1.1.3</version> </dependency> <dependency> <groupId>org.testng</groupId> <artifactId>testng</artifactId> <version>6.8.8</version> <scope>test</scope> </dependency> <dependency> <groupId>com.wattics</groupId> <artifactId>vimsenGDRMdb</artifactId> <version>0.0.1-SNAPSHOT</version> </dependency> </dependencies>中，存在以下依赖项：

const ItemsToSell = [{"Name":"Cup","Price":"99.99"},{"Name":"IPhone","Price":"99.99"},{
"Name":"Pen","Price":"99.99"}]

function ListItem(props) {
  return <li>{props.value}</li>;
}

function NumberList(props) {
  const a = props.numbers;
  return (
    <ul>
      {a.map((number) =>
        <ListItem  value={ItemsToSell[number].Name} />
      )}
    </ul>
  );
}

const numbers = [0,1, 2];
ReactDOM.render(
  <NumberList numbers={numbers} />,
  document.getElementById('root')
);

事实证明，Glassfish的配置存在问题。我在tomcat8上部署并正常工作。

JSON反序列化从测试开始，但不从servlet开始
