建造者优化传递参数，怎么才能不new那么一下？请教大家

关于建造者模式优化传参，我看lombok是这样的

@Builder
@Data
public class TestBuilder {

    private String name;
    private String value;
}

使用

TestBuilder.builder().****.build();

我自己写的，有点问题，就是每次都要先new 一下，请问大家怎么改进。

NCBuilder ncBuilder = new NCBuilder.Builder().***.build();

附上建造者类型

public class NCBuilder {
    private Command cmd;
    private WebClient client;
    private String version;
    private JsonObject ncAcctContext;
    private String ncUrl;
    private String ip;
    private int port;
    private boolean isAsyn;
    private String protocol;
    //私有构造方法
    private NCBuilder(Builder builder){
        this.cmd = builder.cmd;
        this.client=builder.client;
        this.version=builder.version;
        this.ncAcctContext=builder.ncAcctContext;
        this.ncUrl=builder.ncUrl;
        this.ip=builder.ip;
        this.port=builder.port;
        this.isAsyn=builder.isAsyn;
        this.protocol=builder.protocol;
    }
    public static final class Builder {

        private Command cmd;
        private WebClient client;
        private String version;
        private JsonObject ncAcctContext;
        private String ncUrl;
        private String ip;
        private int port;
        private boolean isAsyn;
        private String protocol;

        public Builder cmd(Command cmd) {
            this.cmd = cmd;
            return this;
        }
        public Builder client(WebClient client) {
            this.client = client;
            return this;
        }
        public Builder version(String version) {
            this.version = version;
            return this;
        }
        public Builder ncAcctContext(JsonObject ncAcctContext) {
            this.ncAcctContext = ncAcctContext;
            return this;
        }
        public Builder ncUrl(String ncUrl) {
            this.ncUrl = ncUrl;
            return this;
        }
        public Builder ip(String ip) {
            this.ip = ip;
            return this;
        }
        public Builder port(int port) {
            this.port = port;
            return this;
        }
        public Builder isAsyn(boolean isAsyn) {
            this.isAsyn = isAsyn;
            return this;
        }
        public Builder protocol(String protocol) {
            this.protocol = protocol;
            return this;
        }
        //使用构建者创建NCBuilder对象
        public NCBuilder build() {
            return new NCBuilder(this);
        }

    }

    public Command getCmd() {
        return cmd;
    }

    public void setCmd(Command cmd) {
        this.cmd = cmd;
    }

    public WebClient getClient() {
        return client;
    }

    public void setClient(WebClient client) {
        this.client = client;
    }

    public String getVersion() {
        return version;
    }

    public void setVersion(String version) {
        this.version = version;
    }

    public JsonObject getNcAcctContext() {
        return ncAcctContext;
    }

    public void setNcAcctContext(JsonObject ncAcctContext) {
        this.ncAcctContext = ncAcctContext;
    }

    public String getNcUrl() {
        return ncUrl;
    }

    public void setNcUrl(String ncUrl) {
        this.ncUrl = ncUrl;
    }

    public String getIp() {
        return ip;
    }

    public void setIp(String ip) {
        this.ip = ip;
    }

    public int getPort() {
        return port;
    }

    public void setPort(int port) {
        this.port = port;
    }

    public boolean isAsyn() {
        return isAsyn;
    }

    public void setAsyn(boolean asyn) {
        isAsyn = asyn;
    }

    public String getProtocol() {
        return protocol;
    }

    public void setProtocol(String protocol) {
        this.protocol = protocol;
    }
}

public class NCBuilder {
    private String ip;
    private int port;

    //私有构造方法
    private NCBuilder(Builder builder) {
        this.ip = builder.ip;
        this.port = builder.port;
    }

    public static Builder builder(){
        return new Builder();
    }
    public static final class Builder {
        private String ip;
        private int port;

        public Builder ip(String ip) {
            this.ip = ip;
            return this;
        }

        public Builder port(int port) {
            this.port = port;
            return this;
        }

        //使用构建者创建NCBuilder对象
        public NCBuilder build() {
            return new NCBuilder(this);
        }

    }

    public String getIp() {
        return ip;
    }

    public void setIp(String ip) {
        this.ip = ip;
    }

    public int getPort() {
        return port;
    }

    public void setPort(int port) {
        this.port = port;
    }
    
}

使用

NCBuilder ncBuilder =  NCBuilder.builder().ip("localhost").port(8080).build();

超过三个参数就建议使用POJO的方式进行传参，然后如果参数特别多的话，偶尔有使用不到的参数可以传null过去。当然在你后续的方法里面处理一下以防止空指针。
