求教Postgresql在jdbc处理bit(1)字段的预处理解决方案

1.建表语句：

CREATE TABLE public.h_user (id serial4 not null,username varchar(50) NULL,"password" varchar(64) NULL,nickname varchar(60) NULL,email varchar(255) NULL,gender bit(1) NULL,height float4 NULL,CONSTRAINT user_pkey PRIMARY KEY (id)
);

2.使用以下方式的预处理方式都报错了

求指教怎么使用预处理PreparedStatement 设置bit(1)的值插入到库中。

package com.health.util;
import java.sql.*;public class bitTest {public static void main(String[] args) {// 数据库连接信息String url = "jdbc:postgresql://localhost:5432/postgres";//加 tinyInt1isBit=false 参数也是报错
//            String url = "jdbc:postgresql://localhost:5432/postgres?tinyInt1isBit=false";String username = "postgres";String password = "postgres";// SQL语句String sql = "insert into h_user (username, password, gender,height) values(?,?,?,?)";try {// 加载并注册JDBC驱动Class.forName("org.postgresql.Driver");// 建立数据库连接try (Connection conn = DriverManager.getConnection(url, username, password);// 创建PreparedStatementPreparedStatement pstmt = conn.prepareStatement(sql)) {pstmt.setString(1, "ztt");pstmt.setString(2, "123456");// 设置bit(1)值，这里下面设置的情况都报错
//                    pstmt.setObject(3, new Boolean(true));
//                    pstmt.setObject(3, true,Types.BIT);
//                    pstmt.setObject(3,new Byte("1"));
//                    pstmt.setObject(3, new Short("1"),Types.BIT);
//                    pstmt.setObject(3,1);pstmt.setObject(3,1,Types.BIT);pstmt.setFloat(4, 170);// 执行SQL语句pstmt.executeUpdate();}} catch (Exception e) {e.printStackTrace();}}
}

3.可以先用sql拼接实现功能

package com.health.util;
import java.sql.*;public class bitTest {public static void main(String[] args) {// 数据库连接信息String url = "jdbc:postgresql://localhost:5432/postgres";String username = "postgres";String password = "postgres";// SQL语句  也可以把0::bit替换成cast(1 as bit(1))也可设置成功String sql = "insert into h_user (username, password, gender,height) values('ztt1','123',0::bit,172)";try {// 加载并注册JDBC驱动Class.forName("org.postgresql.Driver");try (Connection conn = DriverManager.getConnection(url, username, password);// 创建StatementStatement stat = conn.createStatement()) {// 执行SQL语句int result = stat.executeUpdate(sql);}} catch (Exception e) {e.printStackTrace();}}
}
