1.需要官網下載jar包

2執行jar包，新增到eclipse目錄下

3然後重啟一下eclipse,

4最重要的是需要在maven中引入

比較一下：

原來的程式碼

public class EnergySource {

	private String energySourceId;
	private String fuel;
	private String industrialWater;
	private String gas;
	private String naturlGas;
	private String steam;
	private String oxygenNitrogen;
	private String compressedAir;
	private String dynamicMedium;
	public String getEnergySourceId() {
		return energySourceId;
	}
	public String getFuel() {
		return fuel;
	}
	public String getIndustrialWater() {
		return industrialWater;
	}
	public String getGas() {
		return gas;
	}
	public String getNaturlGas() {
		return naturlGas;
	}
	public String getSteam() {
		return steam;
	}
	public String getOxygenNitrogen() {
		return oxygenNitrogen;
	}
	public String getCompressedAir() {
		return compressedAir;
	}
	public String getDynamicMedium() {
		return dynamicMedium;
	}
	public void setEnergySourceId(String energySourceId) {
		this.energySourceId = energySourceId;
	}
	public void setFuel(String fuel) {
		this.fuel = fuel;
	}
	public void setIndustrialWater(String industrialWater) {
		this.industrialWater = industrialWater;
	}
	public void setGas(String gas) {
		this.gas = gas;
	}
	public void setNaturlGas(String naturlGas) {
		this.naturlGas = naturlGas;
	}
	public void setSteam(String steam) {
		this.steam = steam;
	}
	public void setOxygenNitrogen(String oxygenNitrogen) {
		this.oxygenNitrogen = oxygenNitrogen;
	}
	public void setCompressedAir(String compressedAir) {
		this.compressedAir = compressedAir;
	}
	public void setDynamicMedium(String dynamicMedium) {
		this.dynamicMedium = dynamicMedium;
	}
	@Override
	public String toString() {
		return "EnergySource [energySourceId=" + energySourceId + ", fuel=" + fuel + ", industrialWater="
				+ industrialWater + ", gas=" + gas + ", naturlGas=" + naturlGas + ", steam=" + steam
				+ ", oxygenNitrogen=" + oxygenNitrogen + ", compressedAir=" + compressedAir + ", dynamicMedium="
				+ dynamicMedium + "]";
	}
	
}
 

加註解的程式碼

import lombok.Data;

@Data
public class EnergySource {

	private String energySourceId;
	private String fuel;
	private String industrialWater;
	private String gas;
	private String naturlGas;
	private String steam;
	private String oxygenNitrogen;
	private String compressedAir;
	private String dynamicMedium;
	
}
