sl4j整合swagger

slf4j是一个日志框架，而Swagger是一个API文档生成工具，它们之间并没有直接的整合关系。不过，我们可以通过在项目中引入swagger-core和swagger-annotations依赖，然后在代码中使用注解来生成API文档，并且使用slf4j来记录日志。

具体实现步骤如下：

1. 在pom.xml文件中添加以下依赖：

<dependency>
    <groupId>io.swagger.core.v3</groupId>
    <artifactId>swagger-core</artifactId>
    <version>2.1.5</version>
</dependency>

<dependency>
    <groupId>io.swagger.core.v3</groupId>
    <artifactId>swagger-annotations</artifactId>
    <version>2.1.5</version>
</dependency>

<dependency>
    <groupId>org.slf4j</groupId>
    <artifactId>slf4j-api</artifactId>
    <version>1.7.30</version>
</dependency>

<dependency>
    <groupId>ch.qos.logback</groupId>
    <artifactId>logback-classic</artifactId>
    <version>1.2.3</version>
</dependency>

2. 在代码中使用swagger注解来生成API文档，例如：

@GET
@Path("/{id}")
@Produces(MediaType.APPLICATION_JSON)
@ApiOperation(value = "Get user by ID", notes = "Returns a user by ID", response = User.class)
@ApiResponses(value = {
        @ApiResponse(code = 200, message = "Successful retrieval of user entity", response = User.class),
        @ApiResponse(code = 404, message = "User entity not found"),
        @ApiResponse(code = 500, message = "Internal server error")})
public Response getUserById(
        @ApiParam(value = "ID of user to return", required = true) @PathParam("id") Long id) {
    User user = userService.getUserById(id);
    if (user == null) {
        throw new NotFoundException("User not found");
    }
    return Response.ok(user).build();
}

3. 在代码中使用slf4j来记录日志，例如：

private static final Logger LOGGER = LoggerFactory.getLogger(UserService.class);

public User getUserById(Long id) {
    LOGGER.info("Getting user by ID: {}", id);
    return userRepository.findById(id);
}
