#ibatis mybatis sql语句

本文介绍了在XML文件中如何正确处理特殊字符以避免解析错误，通过实例展示了使用CDATA段来包含这些特殊字符的方法，并给出了具体的mapper文件示例代码。

因为这个是xml格式的，所以不允许出现类似“>”这样的字符，但是都可以使用<![CDATA[ ]]>符号进行说明，将此类符号不进行解析 
你的可以写成这个： 

mapper文件示例代码<![CDATA[ when min(starttime)<='12:00' and max(endtime)<='12:00' ]]>   &lt;          <
    &gt;          > 
    &lt;&gt;   <>
    &amp;      &
    &apos;      '
    &quot;      "


delete from syst_log t where  t.operate_time<trunc(sysdate)-90---------错误

delete from syst_log t where <![CDATA[ t.operate_time <trunc(sysdate)-90]]>--------------对

由于在dao层的一个文件写出错了注解，导致了整个项目无法读取数据库。mybatis的这个设定真是糟糕透顶，所以说写ognl表达式来对数据库CRUD的时候 一定要小心。控制台报出的错误如下： Error building SqlSession. The error may exist in com/itheima/travel/dao/FavoriteMapper.java (best guess) ### Cause: org.apache.ibatis.builder.BuilderException:

注意：在SQL语句的WHERE子句中，我们使用了小于号`。在XML中，小于号`是特殊字符，必须转义为`<`。 因此，错误的原因是：在XML文件中直接使用了`符号而没有转义。 ### 解决方案 将`remaining_time 中的`替换为`...

在使用mybatis 时我们sql是写在xml 映射文件中，如果写的sql中有一些特殊的字符的话，在解析xml文件的时候会被转义，但我们不希望他被转义，所以我们要使用&lt;![CDATA[ ]]&gt;来解决。 &lt;![CDATA[ ]]&gt; 是什么，这是XML语法。在CDATA内部的所有内容都会被解析器忽略。 如果文本包含了很多的"&lt;“字符 &lt;=和”&amp;"字符——...

因为这个是xml格式的，所以不允许出现类似“>”这样的字符，但是都可以使用符号进行说明，将此类符号不进行解析  你的可以写成这个：  mapper文件示例代码   <          <     >          >      <>       &      &     &apos;      '     "      "

mybatis-plus: configuration: map-underscore-to-camel-case: false配置不生效
最新发布
10-21
<think>我们正在处理关于MyBatis-Plus中配置`map-underscore-to-camel-case: false`不生效的问题。 根据引用内容，我们知道这个配置通常用于控制数据库字段的下划线命名到Java属性的驼峰命名的自动映射。 但是用户配置为`false`（即关闭驼峰映射）却不生效。 分析可能的原因： 1. 配置位置错误：可能没有在正确的位置配置。 2. 配置属性名错误：MyBatis-Plus和MyBatis的配置项可能有所不同。 3. 多个配置源冲突：可能存在多个配置（如同时使用properties和yaml）导致覆盖。 4. 版本差异：不同版本的MyBatis-Plus配置方式可能不同。 5. 其他配置覆盖：可能有其他配置（如自定义的SqlSessionFactoryBean）覆盖了该设置。 解决方案： 1. 确认配置位置：在MyBatis-Plus中，通常是在application.yml（或application.properties）中配置。 正确的配置方式（以yaml为例）： ```yaml mybatis-plus: configuration: map-underscore-to-camel-case: false ``` 注意：在MyBatis-Plus中，配置前缀是`mybatis-plus`，而不是`mybatis`（引用[4]中用的是`mybatis`，但用户使用的是MyBatis-Plus）。 2. 检查属性名：确保属性名正确。在MyBatis中，配置项是`mybatis.configuration.map-underscore-to-camel-case`，但在MyBatis-Plus中，应该使用`mybatis-plus.configuration.map-underscore-to-camel-case`。 3. 检查是否有多处配置：比如同时使用了properties和yaml，或者在不同的配置文件中重复配置，可能导致冲突。 4. 如果使用自定义配置类：如果在代码中自定义了`SqlSessionFactory`，则需要在代码中显式设置： ```java @Bean public SqlSessionFactory sqlSessionFactory(DataSource dataSource) throws Exception { MybatisSqlSessionFactoryBean sessionFactory = new MybatisSqlSessionFactoryBean(); sessionFactory.setDataSource(dataSource); // 其他配置... org.apache.ibatis.session.Configuration configuration = new org.apache.ibatis.session.Configuration(); configuration.setMapUnderscoreToCamelCase(false); // 这里设置 sessionFactory.setConfiguration(configuration); return sessionFactory.getObject(); } ``` 5. 检查依赖冲突：确保项目中MyBatis和MyBatis-Plus的版本兼容，没有多个版本的冲突。 6. 检查日志：开启MyBatis的日志（如引用[3]中配置`mybatis.configuration.log-impl`），查看实际生效的配置。 7. 如果以上都无效，尝试清除缓存并重新启动项目。 根据引用[3]，用户遇到了配置失效的问题，他们的配置是`mybatis.configuration.map-underscore-to-camel-case=false`，但注意他们使用的是`mybatis`前缀，而用户现在是在MyBatis-Plus项目中，所以应该使用`mybatis-plus`前缀。 因此，用户需要检查配置前缀是否为`mybatis-plus`。 另外，引用[4]给出了一个yaml配置示例，它使用的是`mybatis`前缀，但那是针对纯MyBatis的。在MyBatis-Plus项目中，应该使用`mybatis-plus`作为前缀。 所以，最终的配置应该是： ```yaml mybatis-plus: configuration: map-underscore-to-camel-case: false ``` 如果仍然不生效，考虑是否有其他配置覆盖，或者尝试使用代码配置的方式（如上第4点）。 </think>以下是针对MyBatis-Plus中配置`map-underscore-to-camel-case: false`不生效的解决方案，结合引用内容和常见排查路径： ### 问题原因分析 1. **配置优先级冲突** MyBatis-Plus的配置可能被其他配置覆盖： - 同时存在`mybatis-plus.configuration.*`和`mybatis.configuration.*`时，后者可能覆盖前者[^3] - 代码中手动创建`SqlSessionFactory`会覆盖配置文件设置 2. **配置文件语法错误** - YAML缩进错误导致配置未生效 - Properties文件格式错误（如多余空格） 3. **版本兼容性问题** - MyBatis-Plus版本 < 3.4.0 时配置路径不同 --- ### 解决方案 #### 第一步：检查配置文件 ```yaml # application.yml 正确配置示例 mybatis-plus: configuration: map-underscore-to-camel-case: false # 必须缩进对齐 ``` ```properties # application.properties 正确格式 mybatis-plus.configuration.map-underscore-to-camel-case=false ``` > ⚠️ 注意：**禁止混用`mybatis`和`mybatis-plus`前缀**，如同时存在会按`mybatis` > `mybatis-plus`优先级覆盖[^3] #### 第二步：排查代码覆盖 检查是否在配置类中手动创建了`SqlSessionFactory`： ```java @Bean public SqlSessionFactory sqlSessionFactory(DataSource dataSource) throws Exception { MybatisSqlSessionFactoryBean factory = new MybatisSqlSessionFactoryBean(); factory.setDataSource(dataSource); // 手动创建Configuration会覆盖配置文件 org.apache.ibatis.session.Configuration config = new Configuration(); config.setMapUnderscoreToCamelCase(true); // 此处强制覆盖配置 factory.setConfiguration(config); // 删除此行 return factory.getObject(); } ``` #### 第三步：版本适配（旧版本兼容） MyBatis-Plus版本 < 3.4.0时需改用： ```yaml mybatis-plus: global-config: db-config: column-underline: false # 旧版本参数名 ``` #### 第四步：验证配置生效 1. 添加日志配置检查实际生效值： ```yaml mybatis-plus: configuration: log-impl: org.apache.ibatis.logging.stdout.StdOutImpl [^3] ``` 2. 启动时观察日志输出： ``` ... Loaded Configuration: { mapUnderscoreToCamelCase: false, # 确认此处为false ... } ``` #### 终极方案：强制代码配置 在启动类添加初始化代码： ```java @PostConstruct public void forceConfig() { MybatisConfiguration configuration = new MybatisConfiguration(); configuration.setMapUnderscoreToCamelCase(false); MybatisSqlSessionFactoryBean.setGlobalConfiguration(configuration); } ``` --- ### 典型错误示例 ```yaml # 错误配置1：混合前缀 mybatis: configuration: map-underscore-to-camel-case: true # 会覆盖下面的配置 mybatis-plus: configuration: map-underscore-to-camel-case: false # 无效[^3] # 错误配置2：缩进错误 mybatis-plus: configuration: # 缺少缩进 map-underscore-to-camel-case: false ``` > 📌 **引用说明**：配置文件优先级冲突是失效的主要原因，需确保无覆盖关系[^1][^3]，新版MyBatis-Plus推荐统一使用`mybatis-plus`前缀配置[^4]。 ---
