开发环境：windows10、jdk-13.0.1、apache-maven-3.6.2、PostgreSQL 12、Intellij IDEA2019.2.4
postgres官网：https://www.postgresql.org/
一、创建maven项目my-springboot-template，pom.xml配置文件如下
<?xml version="1.0" encoding="UTF-8"?>

</project>二、application.yml中配置数据库
spring:
application:
name: postgres
datasource:
username: postgres
password: 1234
url: jdbc:postgresql://127.0.0.1:5432/mydb10
driver-class-name: org.postgresql.Driver
type: com.zaxxer.hikari.HikariDataSource
hikari:
maximum-pool-size: 20
max-lifetime: 1800000
idle-timeout: 30000
data-source-properties:
prepStmtCacheSize: 250
prepStmtCacheSqlLimit: 2048
cachePrepStmts: true
useServerPrepStmts: true三、程序引导类
package com.zsx;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
public class MySpringbootTemplateApplication {
public static void main(String[] args) {
SpringApplication.run(MySpringbootTemplateApplication.class, args);
}
}
四、编写测试类
package com.zsx;
import com.alibaba.fastjson.JSON;
import com.google.common.collect.ImmutableMap;
import org.junit.jupiter.api.Test;
import org.junit.jupiter.api.extension.ExtendWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.jdbc.core.JdbcTemplate;
import org.springframework.test.context.junit.jupiter.SpringExtension;
import java.util.Map;
import java.util.UUID;
@SpringBootTest
@ExtendWith(SpringExtension.class)
public class PostgresJdbcTemplateTest {
@Autowired
private JdbcTemplate jdbcTemplate;
@Test
void create() {
String sqlDropDatabase = "DROP DATABASE IF EXISTS my_schema ";
jdbcTemplate.execute(sqlDropDatabase);
String sqlDatabase = "CREATE DATABASE my_schema";
jdbcTemplate.execute(sqlDatabase);
String sqlDrop = "DROP SCHEMA IF EXISTS my_schema CASCADE";
jdbcTemplate.execute(sqlDrop);
String sqlSchema = "CREATE schema my_schema";
jdbcTemplate.execute(sqlSchema);
String sqlTable = "CREATE TABLE my_schema.t_test(\"test_id\" varchar(64), \"test_json\" jsonb)";
jdbcTemplate.execute(sqlTable);
}
@Test
void insert() {
String sql = "INSERT INTO my_schema.t_test VALUES (?, ?::jsonb)";
// 不可变Map
Map<String, String> personMap = ImmutableMap.<String, String> builder()
.put("personId", "126")
.put("name", "Tom")
.put("age", "22")
.put("createTime", "2019-11-02 22:09:23")
.build();
jdbcTemplate.update(sql, new Object[] {UUID.randomUUID().toString(), JSON.toJSONString(personMap)});
// String id = "4495bf53-3cf9-4048-b97e-c1505f7748c0";
// jdbcTemplate.update(sql, new Object[] {id, JSON.toJSONString(personMap)});
}
@Test
void update() {
String sql = "UPDATE my_schema.t_test SET test_json = ?::jsonb WHERE test_id = ?";
// 不可变Map
Map<String, String> personMap = ImmutableMap.<String, String> builder()
.put("personId", "128")
.put("name", "Tom1")
.put("age", "20")
.put("createTime", "2019-11-02 22:10:11")
.build();
String id = "4495bf53-3cf9-4048-b97e-c1505f7748c0";
jdbcTemplate.update(sql, new Object[] {JSON.toJSONString(personMap), id});
}
@Test
void delete() {
String sql = "DELETE FROM my_schema.t_test WHERE test_json ::jsonb->>'age' = ? ";
jdbcTemplate.update(sql, new Object[] {"22"});
}
}
五、运行测试方法create()
