mybatis-plus分页total为0，分页失效，mybatis-plus多租户插件使用_ssm框架mybatisplus page total是0

背景：项目使用mybatis分页插件不生效，以及多租户使用时读取配置异常

分页插件不细述，网上很多方法试了还是不生效，最后修改到当前版本解决，直接上代码

多租户插件使用遇到的问题：

最开始在MyTenantLineHandler中使用 @Value("${tables}"),服务启动时能从配置中心拉取到配置，但在运行时获取到的值为空，试了很多方法都不生效，后面将配置中心的配置在调用MyTenantLineHandler的那一层向下传递配置值，问题解决

租户配置

@Component
@RefreshScope
@ConfigurationProperties(prefix = "saas.tenant")
public class ConfigProperties {
 
	public void setColumn(String column) {
		this.column = column;
	}
	public void setTables(List<String> tables) {
		this.tables = tables;
	}
 
	public String getColumn(){
		return this.column;
	}
	public List<String> getTables(){
		return this.tables;
	}
	private String column="";
 
	private List<String> tables= Lists.newArrayList();
}

TenantLineHandler

public class MyTenantLineHandler implements TenantLineHandler {
	private final ConfigProperties configProperties;
 
	public MyTenantLineHandler(ConfigProperties configProperties) {
		this.configProperties = configProperties;
	}
 
	@Override
	public LongValue getTenantId() {
		Long tenantId = TenantContextHolder.getTenantId();
		return tenantId == null ? new LongValue(-1) : new LongValue(tenantId);
	}
 
	@Override
	public String getTenantIdColumn() {
		return configProperties.getColumn();
	}
 
	@Override
	public boolean ignoreTable(String tableName) {
		return !configProperties.getTables().contains(tableName);
		// return TenantLineHandler.super.ignoreTable(tableName);
	}
}

MybatisPlusConfig
注意：TenantLineInnerInterceptor要添加PaginationInnerInterceptor之前，如果放错了，会出现分页count(*)查询时不会自动加上tenant_id

@Configuration
@AutoConfigureAfter(PageHelperAutoConfiguration.class)
//@EnableTransactionManagement
public class MybatisPlusConfig {
	@Autowired
	private List<SqlSessionFactory> sqlSessionFactoryList;
	@Autowired
	private ConfigProperties configProperties;
 
	@PostConstruct
	public void addMyInterceptor() {
		MybatisPlusInterceptor interceptor = mybatisPlusInterceptor();
		for (SqlSessionFactory factory : sqlSessionFactoryList) {
			factory.getConfiguration().addInterceptor(interceptor);
		}
	}
 
	/**
	 * mybatisplus 分页拦截器
	 * @return
	 */
	public MybatisPlusInterceptor mybatisPlusInterceptor() {
		MybatisPlusInterceptor interceptor = new MybatisPlusInterceptor();
		TenantLineInnerInterceptor tenantLineInnerInterceptor=new TenantLineInnerInterceptor();
		tenantLineInnerInterceptor.setTenantLineHandler(new MyTenantLineHandler(configProperties));
		interceptor.addInnerInterceptor(tenantLineInnerInterceptor);
		interceptor.addInnerInterceptor(new PaginationInnerInterceptor());
		return interceptor;
	}
}
