Jackson JsonMappingException：无法反序列化实例

1. 在 条目* 和 电话中 删除构造函数 *

2. GetEntries results = mapper.readValue(new URL("http://collegewires.com/android/jacksoncw.json"), GetEntries.class);

3. 条目似乎是JSON中的参数。

GetEntries.java

package com.collegewires.jackson;import java.util.List;public class GetEntries{    private List<Entries> entries;    public List<Entries> getEntries(){        return this.entries;    }    public void setEntries(List<Entries> entries){        this.entries = entries;    }}

Entries.java

package com.collegewires.jackson;import java.util.List;public class Entries{    private String address;    private String email;    private String gender;    private String id;    private String name;    private Phone phone;    public String getAddress(){        return this.address;    }    public void setAddress(String address){        this.address = address;    }    public String getEmail(){        return this.email;    }    public void setEmail(String email){        this.email = email;    }    public String getGender(){        return this.gender;    }    public void setGender(String gender){        this.gender = gender;    }    public String getId(){        return this.id;    }    public void setId(String id){        this.id = id;    }    public String getName(){        return this.name;    }    public void setName(String name){        this.name = name;    }    public Phone getPhone(){        return this.phone;    }    public void setPhone(Phone phone){        this.phone = phone;    }}

电话.java

package com.collegewires.jackson;import java.util.List;public class Phone{    private String home;    private String mobile;    private String office;    public String getHome(){        return this.home;    }    public void setHome(String home){        this.home = home;    }    public String getMobile(){        return this.mobile;    }    public void setMobile(String mobile){        this.mobile = mobile;    }    public String getOffice(){        return this.office;    }    public void setOffice(String office){        this.office = office;    }}
