旧系统重构遇到的种种问题
在这三篇文章中，我花了近1个月时间重构了28个微服务，当中遇到的一些问题，但是发布到pretest环境，却还有启动问题，看来系统重构不是那么简单。
8 批量操作有问题
本地是没有这个问题，部署到生产在批量插入的时候却报错，原因视为&allowMultiQueries=true，这个要加上
完成如下

?useUnicode=true&characterEncoding=utf-8&useSSL=false&serverTimezone=Asia/Shanghai&allowMultiQueries=true

check_value:  You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'update acc_assisting_accounting
             SET name = '行政部',
           ' at line 6(str)
assert_method: regex_match

7 提示缺少字段，但数据库添加后，重启服务仍然没有效果
出现这个问题是因为分库后，两个库都需要加上这个字段，只有一个库加了，另外一个库没有加，也是有问题的。

### Cause: java.sql.SQLSyntaxErrorException: Unknown column 'accAccountSet.tax_declare_account' in 'field list'

6 SLF4J: Actual binding is of type [ch.qos.logback.classic.util.ContextSelectorStaticBinder]

解决方案如下，问题出现原因是log相关jar冲突

        <exclusion>

5 No servers available for service: einv-user-server

网关为什么没有找到对应得服务呢？其他得服务都是好的，当前得这个服务有什么特别得地方呢？
出现下面得原因有很多种，有的是jar冲突，有的是如我遇到得情况
因为我拿到代码不是自己写的，所以不清楚情况，

2023-08-09 09:24:11.178  WARN 18516 --- [oundedElastic-5] o.s.c.l.core.RoundRobinLoadBalancer      : No servers available for service: einv-user-server

当register-enabled设置为false,服务没有被发现，因此才出现上面得问题，设置为true就没有问题了。

spring:
  application:
    name:  einv-user-server
  cloud:
    nacos:
      config:
        server-addr: ${nacos.server-addr}
        file-extension: yml
        namespace: ${nacos.namespace}
      discovery:
        server-addr: ${nacos.server-addr}
        namespace: ${nacos.namespace}
        register-enabled: true
        weight: 10000

4 Class path contains multiple SLF4J bindings.

3 java.lang.IllegalArgumentException: Property ‘sqlSessionFactory’ or ‘sqlSessionTemplate’ are required
在重构的过程中，有两个服务器起不了，提示下面的错误，配置什么基本是一致的，为什么这两个应用会出错呢？

Error starting ApplicationContext. To display the conditions report re-run your application with 'debug' enabled.
2023-08-06 10:00:19 ERROR org.springframework.boot.SpringApplication          Application run failed

	at org.springframework.beans.factory.annotation.AutowiredAnnotationBeanPostProcessor$AutowiredFieldElement.inject(AutowiredAnnotationBeanPostProcessor.java:640)

调试一下，看看正常的是怎么运行的

下图就可以看到可以读取到sqlsessionfactory属性

但是错误的是没有sqlsessionfactory和sqlsessiontemplate这两项

可以看到下面的缺少了

 <groupId>com.baomidougroupId>
    <artifactId>dynamic-datasource-spring-boot-starterartifactId>
    <version>3.3.6version>

在datasource下面添加sqlSessionFactory,

import com.baomidou.dynamic.datasource.DynamicRoutingDataSource;

    private DynamicDataSourceProperties properties;

    /**

     * 
4. 影子数据源：shadowDataSource
     */
//    @Lazy
//    @Resource(name = "shardingDataSource")
//    private AbstractDataSourceAdapter shardingDataSource;

    @Bean
    public DynamicDataSourceProvider dynamicDataSourceProvider() {
        Map<String, DataSourceProperty> datasourceMap = properties.getDatasource();
        return new AbstractDataSourceProvider() {
            @Override
            public Map<String, DataSource> loadDataSources() {
                Map<String, DataSource> dataSourceMap = createDataSourceMap(datasourceMap);

                return dataSourceMap;
            }
        };
    }

    /**
     * 将动态数据源设置为首选的
     * 当spring存在多个数据源时, 自动注入的是首选的对象
     * 设置为主要的数据源之后，就可以支持shardingjdbc原生的配置方式了
     */
    @Primary
    @Bean
    public DataSource dataSource(DynamicDataSourceProvider dynamicDataSourceProvider) {
        DynamicRoutingDataSource dataSource = new DynamicRoutingDataSource();
        dataSource.setPrimary(properties.getPrimary());
        dataSource.setStrict(properties.getStrict());
        dataSource.setStrategy(properties.getStrategy());
        dataSource.setProvider(dynamicDataSourceProvider);
        dataSource.setP6spy(properties.getP6spy());
        dataSource.setSeata(properties.getSeata());
        return dataSource;
    }

    @Bean
    public SqlSessionFactory sqlSessionFactory(DynamicDataSource dynamicDataSource) throws Exception
    {
        SqlSessionFactoryBean sessionFactoryBean = new SqlSessionFactoryBean();
        sessionFactoryBean.setDataSource(dynamicDataSource);
        return sessionFactoryBean.getObject();
    }


}

解决这个问题是因为项目中复用了组件,而组件里面增加datasource的配置
解决的办法是搞一个配置开关即可

提示新的错误

Parameter 0 of method sqlSessionFactory in com.whty.acc.saes.server.config.DataSourceConfig required a bean named 'hikariDataSourceForAcc' that could not be found.

下面这个问题，是因为当前工程不需要分表，
于是将sharding-jdbc-spring-boot-starter排除在外即可

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'shardingDataSource' defined in class path resource [org/apache/shardingsphere/shardingjdbc/spring/boot/SpringBootConfiguration.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [javax.sql.DataSource]: Factory method 'shardingDataSource' threw exception; nested exception is java.lang.IllegalArgumentException: Data sources cannot be empty.

2 java.nio.charset.MalformedInputException: Input length = 1
原因为下图，解决方案有两个
一、启动命令采用java -jar -Dfile.encoding=utf-8 acc-transfer-server.jar
二、就是将下图中project encoding改成utf-8

1 org.springframework.beans.factory.UnsatisfiedDependencyException
在windows还原同样的环境，也是这样的错误
就其原因是因为

翻看历史记录,mybatis没有这个配置，因为mybatis通过方式来实现。
