我怎樣才能使用put方法插入數據到我的MySQL數據庫使用寧靜web服務

Question

我使用this tutorrial和我創建此 表（ID，用戶名）打印; 現在我想使用RESTful Web服務

我應該把在內容文本框中輸入要做到這一點插入數據呢？

這是我的油漆類

    @Override

     hash += (id != null ? id.hashCode() : 0); 
     return hash; 
    } 

    @Override 
    public boolean equals(Object object) { 
     // TODO: Warning - this method won't work in the case the id fields are not set 
     if (!(object instanceof Prints)) { 
      return false; 
     } 
     Prints other = (Prints) object; 
     if ((this.id == null && other.id != null) || (this.id != null && !this.id.equals(other.id))) { 
      return false; 
     } 
     return true; 
    } 

    @Override 
    public String toString() { 
     return "entities.Prints[ id=" + id + " ]"; 
    } 

} 

我試圖把使用方法，但我得到這個錯誤

，爲什麼我沒有POST方法在組合框中？

Answer 1

把請求主體部分there.If你要更新一些實體，那麼你應該通過與數據的DTO應該是updated.I沒有經過你link.this部分可以在JSON或XML。（如下圖所示）

<?xml version="1.0" encoding="UTF-8" standalone="yes"?> 
<prints> 
<id>1</id> 
<username>test</username> 
</prints> 

你必須註釋你的DTO可以說printsDTO如下

@XmlRootElement(name = "prints") 
public class PrintsDTO { 
private int id; 
private String username; 
// have getters and setteres for above 
} 

Answer 2

我使用的代碼將數據插入到使用RESTful客戶端應用程序我的RESTful Web服務作爲跟隨

NewJerseyClient client = new NewJerseyClient(); 
     Prints p = new Prints(); 
     p.setId(235); 
     p.setUsername("subhi"); 
     client.create_XML(p); 

，這足以讓我的情況
