Question

我希望从2表中得到2个id（id和manufacturer_id），如下所示：没问题，但如果我改变id=661的参数。网址：http://localhost:9999/TestJersey/rest/test/getID?id=661&manufacturer_id=1

它似乎发生错误，我无法从数据库中获取任何数据。这是我的班级：

这是我的POJO

public class DetailManufacturer {

private Integer id; 
private String name;
private String price;
private Integer manufacturer_id;
private String manufacturer_name;

public DetailManufacturer() {

}

public DetailManufacturer(Integer id, String name, String price, Integer manufacturer_id, String manufacturer_name) {
    this.id = id;
    this.name = name;
    this.price = price;
    this.manufacturer_id = manufacturer_id;
    this.manufacturer_name = manufacturer_name;
}
public Integer getId() {
    return id;
}
public void setId(Integer id) {
    this.id = id;
}
public String getName() {
    return name;
}
public void setName(String name) {
    this.name = name;
}
public String getPrice() {
    return price;
}
public void setPrice(String price) {
    this.price = price;
}
public Integer getManufacturer_id() {
    return manufacturer_id;
}
public void setManufacturer_id(Integer manufacturer_id) {
    this.manufacturer_id = manufacturer_id;
}
public String getManufacturer_name() {
    return manufacturer_name;
}
public void setManufacturer_name(String manufacturer_name) {
    this.manufacturer_name = manufacturer_name;
}

我有调试并看到该行：

if(detailManufacturer.getId() == id && detailManufacturer.getManufacturer_id() == manufacturer_id)

看起来这行不正确，请支持我，非常感谢...
