由於Mybaties對ORACLE數據的支持 中 默認存儲數據庫表的 字段不能保存爲空 web
若是容許保存爲空 則須要指定 參數 jdbcTypeForNullspring
一、配置文件只要在mybatis-config.xml 中添加 這條 代碼便可
<settings>
<setting name="jdbcTypeForNull" value="NULL" />
</settings>
二、SpringBoot若是沒有配置文件的 則須要在 SpringBoot啓動主類上 加上以下代碼
1 /*************對因而ORACLE 數據庫的 mybatis必須增長以下的配置*********Start */ 2 @Bean 3 public ConfigurationCustomizer configurationCustomizer() { 4 return new MybatisPlusCustomizers(); 5 } 6 7 class MybatisPlusCustomizers implements ConfigurationCustomizer { 8 @Override 9 public void customize(org.apache.ibatis.session.Configuration configuration) { 10 configuration.setJdbcTypeForNull(JdbcType.NULL); 11 } 12 } 13 /*************對因而ORACLE 數據庫的 mybatis必須增長以下的配置*********End */
如 Application.javasql
1 package com.leecx; 2 3 import org.apache.ibatis.type.JdbcType; 4 import org.mybatis.spring.boot.autoconfigure.ConfigurationCustomizer; 5 import org.springframework.boot.SpringApplication; 6 import org.springframework.boot.autoconfigure.SpringBootApplication; 7 import org.springframework.context.annotation.Bean; 8 import org.springframework.context.annotation.ComponentScan; 9 10 import tk.mybatis.spring.annotation.MapperScan; 11 12 @SpringBootApplication 13 //掃描 mybatis mapper 包路徑 14 @MapperScan(basePackages = "com.leecx.mapper") 15 //掃描 全部須要的包, 包含一些自用的工具類包 所在的路徑 16 @ComponentScan(basePackages= {"com.leecx", "org.n3r.idworker"}) 17 public class Application { 18 19 /*************對因而ORACLE 數據庫的 mybatis必須增長以下的配置*********Start */ 20 @Bean 21 public ConfigurationCustomizer configurationCustomizer() { 22 return new MybatisPlusCustomizers(); 23 } 24 25 class MybatisPlusCustomizers implements ConfigurationCustomizer { 26 @Override 27 public void customize(org.apache.ibatis.session.Configuration configuration) { 28 configuration.setJdbcTypeForNull(JdbcType.NULL); 29 } 30 } 31 /*************對因而ORACLE 數據庫的 mybatis必須增長以下的配置*********End */ 32 33 public static void main(String[] args) { 34 SpringApplication.run(Application.class, args); 35 } 36 37 38 }
