我的application.properties:

spring.datasource.driverClassName=org.h2.Driver
spring.datasource.url=jdbc:h2:./src/main/resources/asnDB;DB_CLOSE_DELAY=-1;DB_CLOSE_ON_EXIT=FALSE
spring.datasource.user=sa
spring.datasource.password=
spring.h2.console.enabled=true
spring.jpa.hibernate.ddl-auto=create

我有一个data.sql,当我启动spring-project时会加载它.

如何更改application.properties以使数据库持久化？

现在它总是创造一个新的.如果我更改为ddl.auto=create,它也不起作用ddl.auto=update.我知道这会ddl.auto=create覆盖我的数据库,但我不知道如何让它持久化.

在data.sql中有3个插入语句,当我运行项目时,我的数据库中已经有3个插入.然后我通过我的UI插入一个新的并退出项目.当我重新运行项目时,只有最初的3个插入.但应该有4个插入.

我正在使用MAVEN并且已经更改了我的pom.xml依赖项:

<dependency>
        <groupId>com.sun.faces</groupId>
        <artifactId>jsf-api</artifactId>
        <version>2.2.14</version>
        <scope>compile</scope>
    </dependency>
    <dependency>
        <groupId>com.sun.faces</groupId>
        <artifactId>jsf-impl</artifactId>
        <version>2.2.13</version>
        <scope>compile</scope>
        <optional>true</optional>
    </dependency>

至:

<dependency>
        <groupId>org.glassfish</groupId>
        <artifactId>javax.faces</artifactId>
        <version>2.3.0</version>
    </dependency>

但现在我得到一个构建错误:

我确实理解一般的全局和本地内存之间的区别.但我有使用本地内存的问题.

1)通过将全局内存变量转换为本地内存变量需要考虑什么？

2)我如何使用本地障碍？

也许有人可以帮我一个小例子.

我尝试使用本地内存进行jacobi计算,但结果只得到0.也许有人可以给我一个建议.

工作方案:

#define IDX(_M,_i,_j) (_M)[(_i) * N + (_j)]
#define U(_i, _j)     IDX(uL, _i, _j)

__kernel void jacobi(__global VALUE* u, __global VALUE* f, __global VALUE* tmp, VALUE factor) {

int i = get_global_id(0);
int j = get_global_id(1);

int iL = get_local_id(0);
int jL = get_local_id(1);

__local VALUE uL[(N+2)*(N+2)];
__local VALUE fL[(N+2)*(N+2)];

IDX(uL, iL, jL) = IDX(u, i, j);
IDX(fL, iL, jL) = IDX(f, i, j);

barrier(CLK_LOCAL_MEM_FENCE);

IDX(tmp, i, j) = (VALUE)0.25 * ( U(iL-1, jL) + …
